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.
