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

ABSTRACT: 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.

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 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).

Project description: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).
