Crystal structure of bis-(pivaloyl-hydroxamato-κ²O,O')copper(II).

ABSTRACT: Reaction of copper(II) nitrate with pivaloyl-hydroxamic acid yielded the title compound, [Cu(pivHA)₂] (where pivHA^- is pivaloyl hydroxamate, C₅H₁₀NO₂). The centrosymmetric mononuclear complex consists of a Cu^II ion, which is located on a center of inversion, with two coordinated pivaloyl hydroxamate monoanions. The Cu^II ion has a square-planar coordination environment consisting of four O atoms - two carbonyl O atoms and two hydroxamate O atoms from two hydroxamate pivHA^- ligands. The pivHA^- anions are coordinated to copper(II) in a trans-mode, forming two five-membered O,O'-chelate rings.

Crystal structure and Hirshfeld surface analysis of bis-(3-aminopyrazole-κN1)bis-(3-aminopyrazole-κN2)bis-(nitrato-κO)copper(II).

Project description:In the crystal structure of the title compound, [Cu(NO3)2(C3H5N3)4], the CuII atom is situated on an inversion center (Wyckoff position 2c of space group P21/n) and shows an octa-hedral [N4O2] coordination environment. The axial positions are occupied by O atoms of nitrate anions, while the equatorial positions are taken up by the N atoms of four 3-amino-pyrazole ligands. As a result of the tautomerism of the latter, two coordinate with the N1-atom of 3-amino-pyrazole while the other two with the N2-atom. The presence of pyrrole-like N-H groups and amine substituents as donor groups leads to numerous intra- and inter-molecular hydrogen-bonding inter-actions, which were qu-anti-fied by Hirshfeld surface analysis.

Crystal structure of anhydrous poly[bis-(μ2-sarcosinato-κ(3) O,N:O')copper(II)].

Project description:The title compound, [Cu(C3H6NO2)2] n , is a bis-complex of the anion of sarcosine (N-methyl-glycine). The asymmetric unit consists of a copper(II) ion, located on a center of inversion, and one mol-ecule of the uninegative sarcosinate anion. The copper(II) ion exhibits a typical Jahn-Teller distorted [4 + 2] coordination geometry. The four shorter equatorial bonds are to the nitro-gen and carboxyl-ate O atoms of two sarcosinate anions, and the longer axial bonds are to carboxyl-ate O atoms of neighboring complexes. The overall structure is made up from two chains formed by these longer axial Cu-O bonds, one extending parallel to [011] and the other parallel to [0-11]. Each one-dimensional array is connected by the equatorial bridging moieties to the chains on either side, creating an extended two-dimensional framework parallel to (100). There is a single inter-molecular hydrogen-bonding inter-action within the sheets between the amino NH group and an O atom of an adjacent mol-ecule.

Crystal structure of (nitrato-κO)bis-(1,10'-phenanthroline-κ2N,N')copper(II) nitrate gallic acid monosolvate monohydrate.

Project description:The title compound, [Cu(NO3)(C12H8N2)2]NO3·C7H6O5·H2O, consists of a mononuclear complex cation with the central CuII atom in a distorted trigonal-bipyramidal coordination sphere. Two N atoms of two 1,10-phenanthroline ligands occupy the axial sites, and the remaining N atoms of the two ligands, as well as one nitrate O atom the equatorial positions. One mol-ecule each of gallic acid and water are present in the crystal as solvent mol-ecules that do not coordinate to the CuII cation, just as the nitrate counter-anion. In the crystal, inter-molecular O-H⋯O hydrogen bonds, as well as C-H⋯O inter-actions and π-π ring stacking between benzene and pyridine rings [centroid-to-centroid distances = 3.471 (2), 3.559 (2) and 3.790 (2) Å], link the mol-ecules into a three-dimensional network structure.

Crystal structure of tetra-μ-acetato-bis-[(5-amino-2-methyl-sulfanyl-1,3,4-thia-diazole-κN 1)copper(II)].

Project description:The reaction of 2-methyl-thio-5-amino-1,3,4-thia-diazole (Me-SNTD; C3H5N3S2) with copper(II) acetate monohydrate [Cu(OAc)2·H2O; C4H8CuO5] resulted in the formation of the title binuclear compound, [Cu2(C2H3O2)4(C3H5N3S2)2] or [Cu2(OAc)4(Me-SNTD)2]. The structure has triclinic (P ) symmetry with a crystallographic inversion centre located at the midpoint of the line connecting the Cu atoms in the dimer. These two Cu atoms of the dimer [Cu⋯Cu = 2.6727 (6) Å] are held together by four carboxyl-ate groups. Each Cu atom is further coordinated to the N atom of an Me-SNTD mol-ecule and exhibits a Jahn-Teller-distorted octa-hedral geometry. The dimers are connected into infinite chains by hydrogen bonds between the NH (Me-SNTD) and the carboxyl-ate groups of neighbouring mol-ecules, generating an R 2 2(12) ring motif. The mol-ecules are further linked by C-H⋯π inter-actions between the thia-diazole rings and the methyl groups of the acetate units.

Crystal structure of (pyridine-κN)bis(quinolin-2-olato-κ(2) N,O)copper(II) monohydrate.

Project description:The title complex, [Cu(C9H6NO)2(C5H4N)]·H2O, adopts a slightly distorted square-pyramidal geometry in which the axial pyridine ligand exhibits a long Cu-N bond of 2.305 (3) Å. The pyridine ligand forms dihedral angles of 79.5 (5) and 88.0 (1)° with the planes of the two quinolin-2-olate ligands, while the dihedral angle between the quinoline groups of 9.0 (3)° indicates near planarity. The water mol-ecule connects adjacent copper complexes through O-H⋯O hydrogen bonds to phenolate O atoms, forming a network inter-connecting all the complexes in the crystal lattice.

Crystal structure of μ-4-oxidobenzoato-κ2O1:O4-bis-[bis-(1,10-phenanthroline-κ2N,N')copper(II)] bis-(4-hy-droxy-benzoate) 7.5-hydrate.

Project description:The title hydrated complex, [Cu2(C7H4O3)(C12H8N2)4](C7H5O3)2·7.5H2O, is composed of dinuclear CuII complex cations, noncoordinating 4-hy-droxy-benzoate anions and water mol-ecules of crystallization. In the dinuclear complex cation, the CuII ions are bridged by a 4-oxidobenzoate ligand and thus each metal ion is five-coordinated by two chelating 1,10-phenanthroline (phen) mol-ecules and one anionic O atom in a distorted trigonal-bipyramid geometry. In the crystal, aromatic π-π stacking occurs between phen rings of neighbouring dinuclear CuII complex cations, forming two-dimensional supra-molecular systems parallel to (100).

Crystal structure of bis-(azido-κN)bis-(quinolin-8-amine-κ2N,N')iron(II).

Project description:The search for new mol-ecular materials with inter-esting magnetic properties using the pseudohalide azide ion and quinolin-8-amine (aqin, C9H8N2) as a chelating ligand, led to the synthesis and structure determination of the title complex, [Fe(N3)2(C9H8N2)2]. The complex shows an octa-hedral geometry, with the FeII atom surrounded by six N atoms; the two N3- anions coordinate in a cis configuration, while the remaining N atoms originate from the two quinolin-8-amine ligands with the quinoline N atoms lying on opposite sides of the Fe atom. The crystal packing is dominated by layers of hydro-philic and aromatic regions parallel to the ac plane, stabilized by a two-dimensional hydrogen-bonded network and π-π stacking.

Crystal structure of bis-[2-(benzo-thia-zol-2-yl)phenolato-κ(2) N,O]copper(II).

Project description:In the title complex, [Cu(C13H8NOS)2], the Cu(II) atom is coordinated by two N atoms and two O atoms from two bidentate benzo-thia-zolphenolate ligands, forming a distorted tetra-hedral geometry [dihedral angle between two N-Cu-O planes: 45.1 (2)°]. The dihedral angles between the benzo-thia-zole ring systems and the phenol rings are 4.1 (4) and 5.8 (4)°, indicating an almost planar geometry. Weak intra- and inter-molecular C-H⋯O hydrogen bonds are observed. In the crystal, weak π-π inter-actions between aromatic and thia-zole rings [centroid-centroid distances = 3.626 (3) and 3.873 (3) Å] link the mol-ecules into a two-dimensional supra-molecular network along the bc plane.

Crystal structure of di-μ-chlorido-bis-[chlorido-bis-(1,2-dimethyl-5-nitro-1H-imidazole-κN3)copper(II)] acetonitrile disolvate.

Project description:1,2-Dimethyl-5-nitro-imidazole (dimetridazole, dimet) is a compound that belongs to a class of nitro-imidazole drugs that are effective at inhibiting the activity of certain parasites and bacteria. However, there are few reports that describe structures of compounds that feature metals complexed by dimet. Therefore, we report here that dimet reacts with CuCl2·H2O to yield a chloride-bridged copper(II) dimer, [Cu2Cl4(C5H7N3O2)4] or [Cu(μ-Cl)Cl(dimet)2]2. In this mol-ecule, the CuII ions are coordinated in an approximately trigonal-bipyramidal manner, and the mol-ecule lies across an inversion center. The dihedral angle between the imidazole rings in the asymmetric unit is 4.28 (7)°. Compared to metronidazole, dimetridazole lacks the hy-droxy-ethyl group, and thus cannot form inter-molecular O⋯H hydrogen-bonding inter-actions. Instead, [Cu(μ-Cl)Cl(dimet)2]2 exhibits weak inter-molecular inter-actions between the hydrogen atoms of C-H groups and (i) oxygen in the nitro groups, and (ii) the terminal and bridging chloride ligands. The unit cell contains four disordered aceto-nitrile mol-ecules. These were modeled as providing a diffuse contribution to the overall scattering by SQUEEZE [Spek (2015 ▸). Acta Cryst. C71, 9-18], which identified two voids, each with a volume of 163 Å3 and a count of 46 electrons, indicative of a total of four aceto-nitrile mol-ecules. These aceto-nitrile mol-ecules are included in the chemical formula to give the expected calculated density and F(000).

Crystal structure of trans-bis-[2-(1H-benzotriazol-1-yl)acetato-κO]bis-(ethano-lamine-κ2 N,O)copper(II).

Project description:The reaction of 2-(1H-benzotriazol-1-yl)acetic acid (HBTA; C8H7N3O2) and mono-ethano-lamine (MEA; C2H7NO) with CuCl2·2H2O resulted in the formation of the title complex, [Cu(C8H6N3O2)2(C2H7NO)2] or [Cu(BTA)2(MEA)2]. Its asymmetric unit comprises one BTA anion coordin-ating to the Cu2+ cation (site symmetry ) through the carboxyl O atom, and one MEA ligand chelating the metal cation by two heteroatoms (O and N). The equatorial Cu-O and Cu-N bond lengths are similar at 2.029 (1) and 1.980 (2) Å, respectively, while the length of the axial Cu-O bond is considerably greater [2.492 (2) Å], as is typical for Jahn-Teller-distorted systems. An intra-molecular hydrogen bond is present between the hy-droxy group of the MEA ligand and the non-coordinating O atom of the carboxyl-ate group. Inter-molecular hydrogen bonding involving the amino function of the MEA ligand and the carboxyl-ate group results in eight-membered rings with an R 2 2(8) graph-set motif. The mol-ecules are further linked by C-H⋯π inter-actions involving the triazole rings and methyl-ene groups of MEA, thus generating an overall three-dimensional supra-molecular framework.
