Tetra-kis(μ-naphthalene-1-acetato-1:2κO:O')bis-(naphthalene-1-acetato)-1κO,O';2κO,O'-bis-(1,10-phenanthroline)-1κN,N';2κN,N'-europium(III)samarium(III).

ABSTRACT: In the title compound, [EuSm(C(12)H(9)O(2))(6)(C(12)H(8)N(2))(2)], the metal site is statistically occupied (50:50) by Eu and Sm atoms, forming a centrosymmetric complex. The metal site is nine-coordinate, in a distorted monocapped square-anti-prismatic coordination geometry. Mol-ecules are linked into three chains by C-H⋯π interactions and C-H⋯O hydrogen bonds. The combination of these chains generates a three-dimensional framework structure. One of the bridging naphthalene-1-ace-tate ligands was found to be disordered over two sites; the site occupancies for the naphthylmethyl group refined to 0.628 (14) and 0.372 (14).

Bis(μ-2-fluoro-benzoato-1:2κO:O')(2-fluoro-benzoato-1κO,O')(2-fluoro-benzoato-2κO)dinicotinamide-1κN,2κN-dizinc(II)-2-fluoro-benzoic acid (1/1).

Project description:The asymmetric unit of the title compound, [Zn(2)(C(7)H(4)FO(2))(4)(C(6)H(6)N(2)O)(2)]·C(7)H(5)FO(2), consists of a binuclear Zn(II) complex bridged by two carboxyl groups of 2-fluoro-benzoate (FB) anions and a 2-fluoro-benzoic acid mol-ecule. The two bridging FB anions, one chelating FB anion and one nicotinamide (NA) ligand coordinate to one Zn cation with a distorted square-pyramidal geometry, while the two bridging FB anions, one monodentate FB anion and one NA ligand coordinate to the other Zn cation with a distorted tetra-hedral geometry. Within the binuclear mol-ecule, the pyridine rings are oriented at a dihedral angle of 19.41 (14)°. In the crystal structure, the uncoordinated 2-fluorobenzoic acid mol-ecules are linked by O-H⋯O hydrogen bonding, forming centrosymmetric supra-molecular dimers. Inter-molecular N-H⋯O hydrogen bonds link the complex mol-ecules into a three-dimensional network. The π-π contacts between nearly parallel pyridine and benzene rings [dihedral angles of 19.41 (14) and 12.72 (16)°, respectively, centroid-centroid distances = 3.701 (2) and 3.857 (3) Å] may further stabilize the crystal structure. The fluorine atoms in two FB ligands are disordered over two positions, with occupancy ratios of 0.70:0.30.

Project description:In the title heteronuclear Zn(II)-Sm(III) complex, [SmZn(C(18)H(18)N(2)O(4))(NO(3))(3)(CH(3)CH(2)OH)], with the hexa-dentate Schiff base compartmental ligand N,N'-bis-(3-methoxy-salicyl-idene)ethyl-enediamine (H(2)L), the Sm(III) and Zn(II) ions are triply bridged by two phenolate O atoms from the Schiff base ligand and one nitrate anion. The five-coordinate Zn(II) ion is in a square-pyramidal geometry formed by the donor centers of two imine N atoms, two phenolate O atoms and one of the bridging nitrate O atoms. The Sm(III) center is in a ten-fold coordination of O atoms, involving the phenolate O atoms, two meth-oxy O atoms, one ethanol O atom, and two O atoms from two nitrate anions and one from the bridging nitrate anion. In the crystal, inter-molecular O-H⋯O and C-H⋯O inter-actions generate a layer structure extending parallel to (101).

Octa-akis(4-amino-pyridine)-1κN,2κN-aqua-2κO-μ-carbonato-1:2κO,O':O''-dinickel(II) dichloride penta-hydrate.

Project description:In the title compound, [Ni(2)(CO(3))(C(5)H(6)N(2))(8)(H(2)O)]Cl(2)·5H(2)O, one of the the Ni(II) ions is six-coordinated in a distorted octa-hedral geometry, with the equatorial plane defined by four pyridine N atoms from four amino-pyridine ligands, the axial positions being occupied by one water O and a carbonate O atom. The other Ni(II) ion is also six-coordinated, by four other pyridine N atoms from four other amino-pyridine ligands and two carbonate O atoms to complete a distorted octa-hedral geometry.

Project description:The crystal structure of the title compound, [Ni(2)Cd(C(17)H(16)N(2)O(2))(2)(C(2)H(3)O(2))(2)(C(3)H(7)NO)(2)], contains discrete centrosymmetric hetero-trinuclear mol-ecules in which Ni/Cd atom pairs are triply bridged via O atoms from the SALPD(2-) [N,N'-bis-(salicyl-idene)-1,3-propane-diaminate] and acetate ligands. The central Cd(II) ion is in a distorted octa-hedral coordination environment formed by four O atoms from two SALPD(2-) ligands in the equatorial plane and two O atoms of two symmetry-related acetate ligands in the axial positions. The symmetry-related Ni(II) ions are in slightly distorted octa-hedral environments, coordinated by two O and two N atoms from tetra-dendate SALPD(2-) ligands in the equatorial plane, while the axial positions are occupied by O atoms from a dimethyl-formamide and an acetate ligand. This results in the formation of three edge-shared octa-hedra in which the Ni⋯Cd distance is 3.1482 (15) Å. The crystal structure is stabilized by weak C-H⋯O hydrogen bonds.

Project description:In the title trinuclear cobalt-terbium complex, [Co(2)Tb(C(4)H(5)O(2))(6)(NO(3))(C(10)H(8)N(2))(2)], the central Tb(III) and each of the Co(II) ions are bridged by three carboxyl-ate groups of the methacrylate anions. The Tb(III) cation is coordinated by six O atoms from six methacrylate anions and two O atoms from a chelating nitrate anion in a distorted square-anti-prismatic geometry. Each Co(II) ion is coordinated by three O atoms from three methyl-acrylate anions and two N atoms of a 2,2'-bypiridine ligand in a distorted square-pyramidal geometry. In the crystal structure, π-π stacking between the pyridine rings [centroid-centroid distances = 3.682 (8) and 3.760 (8) Å] is observed and weak inter-molecular C-H⋯O hydrogen bonding is also present.

μ-4,4'-Bipyridyl-1:2κN:N'-methanol-2κO-tetrakis(tri-tert-butoxy-silanethiol-ato)-1κO,S;2κS-dizinc(II).

Project description:The title compound, [Zn(2)(C(12)H(27)O(3)SSi)(4)(C(10)H(8)N(2))(CH(4)O)], is a binuclear complex with the two Zn(II) atoms linked via a bridging 4,4'-bipyridyl ligand. One of the Zn(II) atoms is penta-coordinated by two O,S-chelating tri-tert-butoxy-silanethiol-ate units and one N atom of a 4,4'-bipyridine ligand, and the other Zn(II) atom is tetra-hedrally coordinated by two tri-tert-butoxy-silanethiol-ate anions acting as monodentate S ligands, the methanol O atom and the other N atom of the 4,4'-bipyridine ligand. This non-symmetrical coordination induces twisting and bending in the 4,4'-bipyridine ligand and introduces chirality into the system. The crystal studied exhibits inversion twinning. One tert-butyl group is disordered approximately equally over two positions.

Triaqua-1κO-μ-cyanido-1:2κN:C-penta-cyanido-2κC-tetra-kis-(dimethyl-formamide-1κO)-1-holmium(III)-2-iron(III) monohydrate.

Project description:In the bimetallic cyanide-bridged title complex, [Fe(0.98)HoRu(0.02)(CN)(6)(C(3)H(7)NO)(4)(H(2)O)(3)]·H(2)O, the Ho(III) ion is in a slightly distorted square-anti-prismatic arrangement formed by seven O atoms from four dimethyl-formamide (DMF) mol-ecules and three water mol-ecules, and one N atom from a bridging cyanide group connected with the Fe(III) atom which is octa-hedrally coordinated by six cyanide groups. In the crystal, mol-ecules are held together through O-H⋯N and O-H⋯O hydrogen-bonding inter-actions to form a three-dimensional framework. Elemental analysis of one of the precursors and the crystal shows that there is a slight contamination of Fe by Ru. The Fe site displays, therefore, small substitutional disorder with site-occupancy factors Fe/Ru = 0.98:0.02. The two methyl groups of two dimethyl-formamide ligands are positionally disordered with site-occupancy factors of 0.44 (3):0.56 (3) and 0.44 (3):0.56 (3).
