A novel Cd(II) coordination polymer with 1,1'-(1,4-butanediyl)diimidazole.

The novel title Cd(II) coordination polymer, poly[[dichlorocadmium(II)]-di-micro-1,1'-(1,4-butanediyl)diimidazole], [CdCl(2)(C(10)H(14)N(4))(2)](n), (I), was obtained by reaction of CdCl(2).2.5H(2)O and 1,1'-(1,4-butanediyl)diimidazole (hereafter L). In (I), each L molecule coordinates to two Cd(II) cations through its two aromatic N atoms, thus acting as a bridging bidentate ligand. The Cd(II) cations, which lie on the inversion centre, are bridged by four L molecules to form a two-dimensional (4,4)-network. The two-dimensional square-grid sheets are superimposed in an offset fashion.
