Catena-Poly[[dichloridozinc(II)]-?-2,5-di-4-pyridyl-1,3,4-thia-diazole-?N:N].

ABSTRACT: 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.

Project description:In the title mononuclear complex, [Ni(NCS)(2)(C(12)H(8)N(4)S)(2)(H(2)O)(2)]·2H(2)O, the Ni(II) atom is located on an inversion center and is octa-hedrally coordinated by four N atoms from two 2,5-di-4-pyridyl-1,3,4-thia-diazole (bpt) ligands and two thio-cyanate mol-ecules forming the equatorial plane; the axial positions are occupied by two O atoms of coordinated water mol-ecules. O-H⋯O, O-H⋯N and O-H⋯S hydrogen bonds, involving the uncoordinated water molecules, result in the formation of a sheet structure developing parallel to (021).

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[[aquanickel(II)]-μ-pyridine-2,6-dicarboxylato-[aquanickel(II)]-μ-2,5-di-4-pyridyl-1,3,4-thiadiazole].

Project description:The two independent Ni(II) ions in the one-dimensional title complex, [Ni(2)(C(7)H(3)NO(4))(2)(C(12)H(8)N(4)S)(H(2)O)(2)](n) or [Ni(2)(pydc)(2)(bpt)(H(2)O)(2)](n) (H(2)pydc = pyridine-2,6-dicarboxylic acid and bpt = 2,5-di-4-pyrid-yl-1,3,4-thia-diazole), have different coordination environments. One Ni(II) ion is in a slightly-distorted octa-hedral coordination environment formed by three O atoms from two adjacent pydc ligands, two N atoms from bpt and pydc ligands, and one water mol-ecule, while the other Ni(II) ion is in distorted square-pyramidal geometry, coordinated by two O atoms from two carboxyl-ate groups and two N atoms from the pyridine rings of the pydc and bpt ligands in the basal plane, while a coordinated water mol-ecule occupies the apical site. In the crystal structure, the H atoms of both water mol-ecules are involved in inter-molecular hydrogen bonds with the O atoms of uncoordinated carboxyl-ate groups, which link chains into a three-dimensional network.
