Poly[bis-(N,N-dimethyl-acetamide)-1κO,2κO-bis-(μ(4)-thio-phene-2,5-di-car-boxyl-ato-1:2:1':2'κO:O:O:O)dizinc].

ABSTRACT: In the title polymeric complex, [Zn(2)(C(6)H(2)O(4)S)(2)(C(4)H(9)NO)(2)](n), each carboxyl-ate group of the thio-phene-2,5-dicarboxyl-ate dianion bridges a pair of inversion-related dimethyl-acetamide-coordinated Zn(II) atoms, generating a layer motif parallel to (101). The Zn(II) atom shows a distorted square-pyramidal coordination; the apical site is occupied by the O atom of the dimethyl-acetamide mol-ecule, whereas the four basal sites are occupied by carboxyl-ate O atoms. In the crystal, the dimethyl-acetamide mol-ecule is disordered over two positions in a 0.72 (1):0.28 (1) ratio in respect of the C atoms.

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.

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.

Aqua-(2,2'-bipyridine-κN,N')bis-(thio-phene-2-carboxyl-ato-κO)copper(II).

Project description:In the title complex, [Cu(C(5)H(3)O(2)S)(2)(C(10)H(8)N(2))(H(2)O)], the Cu(II) atom is in a distorted square-pyramidal environment, with an Addison τ parameter of 0.07. The coordination geometry is defined by two nitro-gen donors from the 2,2'-bipyridine ligand, two O atoms from two monodentate thio-phene-2-carboxyl-ate ligands and one O atom from the aqua ligand. The latter occupies the elongated apical position. This is different from the related structure of aqua-(1,10-phenanthroline)bis-(thio-phene-2-carboxyl-ato)copper(II) where a carboxyl-ate O atom is in the apical position [Feng et al. (2005 ▶). Z. Kristallogr. New Cryst. Struct.220, 429-430]. The uncoordinated carboxyl-ate O atoms form intra- and inter-molecular hydrogen bonds to the aqua ligand. Two neighbouring 2,2'-bipyridine ligands form a π-stack, with a centroid-centroid distance of 3.683 (2) Å.

Project description:In the title polymeric complex, [Cu(2)(C(6)H(8)O(4))(2)(C(3)H(7)NO)(2)](n), the carboxyl-ate groups of the approximately U-shaped adipate dianion each bridge a pair of inversion-related, DMF-coordinated copper(II) atoms, generating a ribbon motif that runs along the b axis. The geometry of the copper(II) atom is distorted square-pyramidal; the apical site is occupied by the O atom of the DMF mol-ecule whereas the four basal sites are occupied by carboxyl-ate O atoms.

catena-Poly[diimidazolium [bis-(?-pyridine-2,5-dicarboxyl-ato)bis-[diaqua-praseodymate(III)]]-bis-(?-pyridine-2,5-dicarboxyl-ato)].

Project description:The title compound {(C(3)H(5)N(2))(2)[Pr(2)(C(7)H(3)NO(4))(4)(H(2)O)(4)]}(n), has a chain structure featuring a dimeric unit consisting of two Pr(III) atoms within a dodecahedral environment. Each of the metal cations is coordinated by two N atoms and two O atoms from two pyridine-2,5-dicarboxyl-ate ligands, two O atoms from another two pyridine-2,5-dicarboxyl-ate ligands and two water O atoms. The Pr(III) ions are bridged by two ligands along the c axis, forming the dimeric unit, and these are connected by four ligands along the b axis, forming a chain. N-H?O and O-H?O hydrogen bonds are found in the structure.

Guanidinium (aqua-2κO)(4-hydr-oxy-6-carboxy-pyridine-2-carboxyl-ato-2κO,N,O)(μ-4-hydroxy-pyridine-2,6-dicarboxyl-ato-1:2κO,N,O:O)(4-hydroxy-pyridine-2,6-dicarboxyl-ato-1κO,N,O)dizincate(II) dihydrate.

Project description:The title compound, (CH(6)N(3))[Zn(2)(C(7)H(3)NO(5))(2)(C(7)H(4)NO(5))(H(2)O)]·2H(2)O, has an anionic binuclear complex of Zn(II) balanced with a guanidinium cation. There are two uncoord-inated water mol-ecules in the structure. The asymmetric unit of the compound has two different coordination types (the coordination of Zn1 is distorted trigonal-bipyramidal, while that of Zn2 is distorted octahedral) of Zn(II) in the crystal structure that are bridged to each other via one hypydc(2-) group (hypydcH(2) is 4-hydroxy-pyridine-2,6-dicarboxylic acid). A variety of inter-molecular O-H⋯O, N-H⋯O and C-H⋯O hydrogen bonds involving water mol-ecules, cations and anions, and also a weak π-π inter-action [3.798 (1) Å], are responsible for extending the structure into a three-dimensional network.

Syntheses and crystal structures of the cerium-based coordination polymers poly[(acetic acid)bis-(μ-5-carb-oxy-thio-phene-2-carboxyl-ato)bis-(μ-thio-phene-2,5-di-carboxyl-ato)dicerium(III)] and poly[(μ-acetato)-aqua-(μ<sub>4</sub>-thio-phene-2,5-di-carboxyl-ato)cerium(III)].

Project description:The title compounds, [Ce2(C6H3SO4)2(C6H2SO4)2(CH3COOH)] n (1) and [Ce(CH3COO)(C6H2SO4)(H2O)] n (2) were synthesized by solvothermal reaction of Ce(NO3)3·6H2O with 2,5-thio-phenedi-carb-oxy-lic acid (H2TDC, C6H4SO4) and acetic acid in aceto-nitrile or ethanol/water, respectively. These compounds were obtained as single crystals among other crystalline phases. Both compounds belong to the family of three-dimensional coordination polymers. The asymmetric unit of 1 consists of two CeIII cations, two TDC2- dianions, two HTDC- anions and one acetic acid ligand, all of them located in general positions. The two CeIII cations are each coordinated by eight oxygen atoms in the form of distorted square anti-prisms. These are bridged by carboxyl-ate and carb-oxy-lic acid groups, forming mono-periodic hybrid inorganic building units (IBUs), which are connected into a three-dimensional network by the TDC2- and HTDC- ligands. Compound 2 has an asymmetric unit composed of one CeIII cation, one TDC2- dianion, one acetate anion and one water mol-ecule in general positions. The cerium atom is eightfold coordinated by oxygen atoms. Edge-sharing CeO8 polyhedra form a dinuclear IBU (Ce2O14). This IBU is bridged by six TDC2- linkers to nine other IBUs, forming a three-dimensional framework. Both title compounds exhibit additional O-H⋯O hydrogen bonds. Powder X-ray diffraction shows that both compounds were not obtained as pure phases.
