Catena-Poly[[bis-(3-benzoyl-pyridine-κN)zinc(II)]-di-μ-dicyanamido-κN:N].

ABSTRACT: The title compound, [Zn(C(2)N(3))(2)(C(12)H(9)NO)(2)](n), is a polymeric zinc(II) complex with the metal ion located on an inversion centre. The Zn(II) ion is six-coordinated by two N atoms of two 3-benzoyl-pyridine ligands and four N atoms from four dicyanamide ligands, forming a slightly distorted octa-hedral configuration. In the crystal structure, neighboring Zn atoms are linked together by double dicyanamide bridges to form a polymeric zinc(II) complex.

catena-Poly[[bis-(pyridine-κN)cadmium]-di-μ(2)-thio-cyanato-κN:S;κS:N].

Project description:The asymmetric unit of the title compound, [Cd(NCS)(2)(C(5)H(5)N)(2)](n), consists of two crystallographically independent Cd(II) cations, four thio-cyanato anions and four pyridine ligands. The Cd(II) atoms are each coordinated by four N atoms from two pyridine ligands and two thio-cyanato anions, each in a mutually cis orientation, and by two S atoms from two adjacent thio-cyanato anions within a slightly distorted octa-hedral coordination environment. The Cd(II) atoms are μ-1,3-bridged via the thio-cyanato anions into polymeric chains parallel to [001]. The Cd(II)⋯Cd(II) intra-chain separations range between 5.9688 (6) and 6.0195 (6) Å, whereas the shortest Cd(II)⋯Cd(II) inter-chain separations are 7.8272 (7) and 8.6312 (6) Å.

Project description:In the title coordination polymer, [Zn(C(8)H(4)O(4))(C(5)H(5)N)(2)](n), the Zn(II) atom, located on a twofold rotation axis, is tetra-coordinated by two monodentate O atoms from two different carboxyl-ate groups and two pyridyl N atoms, forming a distorted tetra-hedral geometry.

Project description:In the title compound, [Cu(C(2)N(3))(C(10)H(8)N(2)S(2))](n), the Cu(I) atoms are connected by bridging dicyanamide ligands, forming chains parallel to [100]. Each Cu(I) atom displays a tetra-hedral coordination environment, formed by one S atom and three N atoms from one 2-(pyridin-2-yldisulfan-yl)pyridine and two dicyanamide ligands. The crystal structure is stabilized by C-H⋯N hydrogen bonds, forming a three-dimensional network.

catena-Poly[[bis-(pyridine-κN)zinc]-μ-5-carb-oxy-benzene-1,3-di-carboxyl-ato-κ(2) O (1):O (3)].

Project description:The title one-dimensional coordination polymer, [Zn(C9H4O6)(C5H5N)2] n or [Zn(HBTC)(py)2] n , (I), where BTC is benzene-1,3,5-tricarboxylate and py is pyridine, is a solvent-free polymorph of [Zn(HBTC)(py)2]·2C2H5OH [Yaghi et al. (1997 ▶). Chem. Mater. 9, 1074-1076]. Differences in the spatial arrangements and supra-molecular packing of the [Zn(HBTC)(py)2] n chains in the two structures are described. The chain in (I) extends parallel to [100] and is severely puckered, with a Zn⋯Zn distance of 8.3599 (3) Å and a Zn⋯Zn⋯Zn angle of 107.516 (3)°, as a result of hydrogen-bonding inter-actions of the types O-H⋯O and C-H⋯O. There is no evidence for π-π inter-actions in (I). The differences between the solvent-free and solvent-containing structures can be accounted for by the absence of the ethanol solvent mol-ecule and the use of the converging pair of O atoms in the bis-monodentate bridging HBTC(2-) ligand in (I).

The Co(II) atoms are connected by two bridging dicyanamide ligands, resulting in a chain parallel to the c axis. The chains are connected into a three-dimensional network by C-H?N hydrogen bonds.

Project description:In the title complex, {[Zn(C(7)H(3)NO(4))(C(12)H(8)N(2))]·H(2)O}(n), the Zn(II) ion is in a distorted octa-hedral environment, defined by two N atoms from a chelating 1,10-phenanthroline (phen) ligand and one N atom and three O atoms from two pyridine-2,3-dicarboxyl-ate (2,3-pydc) ligands. The bridging 2,3-pydc ligands connect the Zn(II) ions into a chain extending along [010]. O-H⋯O hydrogen bonds between the uncoordinated water mol-ecules and the uncoordinated carboxyl-ate O atoms, as well as π-π inter-actions between the pyridine rings of the phen ligands [centroid-centroid distance = 3.557 (2) Å], are observed.
