Catena-Poly[(?-2-amino-1,3,4-thia-diazole-?N:N)di-?-chlorido-cadmium].

ABSTRACT: In the title coordination polymer, [CdCl(2)(C(2)H(3)N(3)S)](n), the Cd(II) cation is coordinated by four Cl(-) anions and two N atoms from two trans 2-amino-1,3,4-thia-diazole (L) ligands in a distorted octa-hedral geometry. The L ligand and Cl(-) anions bridge adjacent Cd cations, forming a polymeric chain along the b axis; the separation between adjacent Cd cations is 3.619?(1)?Å. In the crystal, the polymeric chains are inter-linking through N-H?Cl hydrogen bonds between the L ligands and Cl(-) anions.

Project description:The title compound, [ZnCl(2)(C(12)H(8)N(4)S)](n), was obtained by crystallization of 2,5-di-4-pyridyl-1,3,4-thia-diazole with ZnCl(2) in an MeOH/CHCl(3) solvent system. The structure contains infinite chains of ZnCl(2) units connected by the bifunctional thia-diazole ligands, with Zn(II) adopting a distorted tetra-hedral coordination geometry. The dihedral angle between the two pyridyl rings in each ligand is 34.3 (1)°, and the dihedral angles between the thia-diazole ring and the two pyridyl rings are 18.3 (2) and 16.1 (2)°. The shortest Zn⋯Zn distance within each polymeric chain is 11.862 (3) Å, while the shortest inter-chain Zn⋯Zn distance is 7.057 (3) Å.

catena-Poly[(dichloridocadmium)-di-?-chlorido-[bis-(morpholinium-?O)cadmium]-di-?-chlorido].

Project description:In the title compound, [Cd(2)Cl(6)(C(4)H(10)NO)(2)](n), the coordination geometry of each Cd(II) ion is distorted octa-hedral, but with quite different coordination environments. One Cd(II) atom is coordinated by four Cl atoms and two O atoms from two morpholinium ligands, while the other is coordinated by six Cl atoms. Adjacent Cd(II) atoms are inter-connected alternately by paired chloride bridges, generating a chain parallel to the a axis. Inter-chain N-H?Cl inter-actions form a two-dimensional network.

catena-Poly[[bis-(nitrato-κO,O')copper(II)]-μ-2,2'-(ethane-1,2-diyldithio)di-1,3,4-thia-diazole-κN:N].

Project description:In the title compound, [Cu(NO(3))(2)(C(6)H(6)N(4)S(4))](n), the Cu(II) atom, occupying a crystallographic inversion centre, is six-coordinated by two N atoms of two 2,2'-[1,2-ethane-diyl-bis-(thio)]bis-[1,3,4-thia-diazole] ligands in trans positions, and four O atoms from two symmetry-related opposite nitrate anions, which are asymmetrically bonded, resulting in a strong distorted octa-hedral geometry of the central atom. The ethane group is equally disordered over two sites via another inversion centre. The bridging bidentate 2,2'-[1,2-ethanediylbis(thio)]bis-[1,3,4-thia-diazole] ligands link the Cu(II) centres into a one-dimensional chain. The chains are inter-connected via inter-molecular S⋯O inter-actions [3.044 (4) and 3.084 (5) Å] and weak C-H⋯O hydrogen bonds, generating a three-dimensional supra-molecular structure.

catena-Poly[cadmium-?-[1,3-bis-(imidazol-1-yl)propane]-di-?-chlorido].

Project description:The title complex, [CdCl(2)(C(9)H(12)N(4))](n), is characterized by the formation of a zigzag chain structure parallel to [001]. In the chain, the Cd(2+) cation is coordinated by four bridging Cl(-) ligands in equatorial positions and two N atoms from symmetry-related and likewise bridging 1,3-bis-(imidazol-1-yl)propane ligands in axial positions, forming a distorted CdCl(4)N(2) octa-hedron.

Project description:In the title compound, {[Cu(C(7)H(8)N(4)S(4))(4)](ClO(4))(2)}(n), the Cu(II) atom, occupying a crystallographic inversion centre, is six-coordinated by six N atoms of three symmetry-related 2,2'-(propane-1,3-diyldithio)bis-(1,3,4-thia-diazole) (L) ligands in a slightly distorted octa-hedral geometry. The ligand L adopts two kinds of coordination modes in the crystal structure; one is a monodentate coordination mode and serves to complete the octa-hedral coordination of the Cu atom and the other is an N:N'-bidentate bridging mode in a trans configuration, bridging Cu atoms via translation symmetry along the b axis into a chain structure. The perchlorate ions serve as acceptors for inter-molecular C-H?O hydrogen bonds, which link the chains into a three-dimensional network.

catena-Poly[[bis[quinazolin-4(3H)-one-?N]cadmium(II)]-di-?-chlorido].

Project description:The asymmetric unit of the title compound, [CdCl(2)(C(8)H(6)N(2)O)(2)](n), consists of one mol-ecule of the 3H-quinazolin-4-one ligand, one Cd(2+) cation, which is located on a twofold axis, and one chlorido ligand in a general position. The latter bridges metal cations, forming a one-dimensional polymer along the b axis. The Cd?Cd distance along the chain is 3.7309?(7)?Å. The octa-hedral coordination around the metal is completed by two ligands in a trans axial geometry which coordinate through the N atom in 1 position. Moderately strong classical N-H?O hydrogen bonds around crystallographic inversion centers cross-link adjacent polymeric chains.
