Catena-Bis(μ-chloro)-(κ-O, κ-N-{2-thenoylhydrazine})-cadmium(II), a Novel Cadmium Coordination Polymer

Abstract

The title compound, [CdCl2(C5H6N2OS)] n , crystallizes in the polar space group R3c with the crystal cell parameters a = 23.363(3) A, c = 9.5560(19) A, V = 4,478.4(13) A3 and Z = 18. Each cadmium is coordinated to four bridging chloro ligands, the carbonyl oxygen and the terminal nitrogen atom of a 2-thenoylhydrazine ligand. The chelating coordination by the latter moiety implies a distorted cis octahedral arrangement around the metal center. The resulting helical polymer chains in the direction of the crystallographic c axis are cross-linked by the N–H···O hydrogen bonds to a three-dimensional network. catena-Bis(μ-chloro)-(κ-O, κ-N-{2-thenoylhydrazine})-cadmium(II) crystallizes in the polar space group R3c as a helical polymer which expands along the c axis.
