Catena-Poly[[dichloridozinc(II)]-?-1,1'-(hexane-1,6-di-yl)diimidazole-?N:N].

ABSTRACT: In the structure of the polymeric title compound, [ZnCl(2)(C(12)H(18)N(4))](n) or [ZnCl(2)(L)](n), where L = 1,1'-(hexane-1,6-di-yl)diimidazole, the Zn(II) centre is coordinated by two N atoms of two different L ligands and by two chloride anions in a distorted tetra-hedral geometry. The organic ligand links adjacent metals to form a polymeric chain along the c axis. The chains are further connected into layers parallel to the bc plane by inter-molecular C-H?Cl hydrogen bonds. Two C atoms of the central hexyl chain are disordered over two positions with site-occupancy factors of 0.5.

catena-Poly[[dichloridozinc(II)]-?-[1,1'-(butane-1,4-di-yl)diimidazole-?N:N]].

Project description:The title one-dimensional coordination polymer, [ZnCl(2)(C(10)H(14)N(4))](n), was synthesized by hydro-thermal methods from ZnCl(2) and 1,1'-(butane-1,4-di-yl)diimidazole. The Zn atom is coordinated by two chloride ions and two N atoms from two symmetry-independent organic ligands and shows a distorted tetra-hedral coordination geometry. The 1,1'-(butane-1,4-di-yl)diimidazole ligands are located around two sets of inversion centers and bridge Zn(II) ions, forming a zigzag polymeric chain. C-H?Cl hydrogen bonding results in the formation of a three-dimensional supra-molecular network.

Project description:In the title compound, {[Cu(C(10)H(14)N(4))(2)(H(2)O)(2)](NO(3))(2)}(n), the Cu(II) ion lies on an inversion center and is six-coordinated in an octa-hedral environment by four N atoms from four different 1,1'-butane-1,4-diyldiimidazole ligands and two O atoms from the two water mol-ecules. Bridging by the ligands results in a ribbon structure. Adjacent ribbons are linked to the nitrate anions via O-H?O hydrogen bonds, forming layers. One nitrate O atom is disordered equally over two positions.

catena-Poly[[[bis-(4-amino-benzoato-κO)copper(II)]-μ-1,1'-(pentane-1,5-di-yl)diimidazole] trihydrate].

Project description:In the title compound, {[Cu(C(7)H(6)NO(2))(2)(C(11)H(16)N(4))]·3H(2)O}(n), each Cu(II) atom is coordinated by two O atoms from two 4-amino-benzoate anions, and two N atoms from two different 1,1'-(pentane-1,5-di-yl)diimidazole (biim-5) ligands, to furnish a distorted square-planar geometry. The biim-5 ligand coordinates to two copper(II) cations, acting as a bridging ligand; as a result the copper(II) cations are connected to form an infinite chain structure. The polymeric chains are linked through a variety of hydrogen bonds to form a three-dimensional structure.

The 1,1'-(butane-1,4-di-yl)diimidazole ligand and the cyclo-hexane-1,4-dicarboxyl-ate dianion bridge metal centres, forming a two-dimensional (4,4) network. The network is consolidated by O-H?O hydrogen bonds between the statistically occupied water molecules and O atoms of the two carboxylate groups.

Adjacent nets are linked to the chloride anions and uncoordinated water mol-ecules via O-H⋯Cl and O-H⋯O hydrogen bonds, generating a three-dimensional supra-molecular structure.
