catena-Poly[[dichloridozinc(II)]-μ-[1,1′-(butane-1,4-diyl)diimidazole-κ2N3:N3′]]

The title one-dimensional coordination polymer, [ZnCl2(C10H14N4)]n, was synthesized by hydrothermal methods from ZnCl2 and 1,1′-(butane-1,4-diyl)diimidazole. The Zn atom is coordinated by two chloride ions and two N atoms from two symmetry-independent organic ligands and shows a distorted tetrahedral coordination geometry. The 1,1′-(butane-1,4-diyl)diimidazole ligands are located around two sets of inversion centers and bridge ZnII ions, forming a zigzag polymeric chain. C—H...Cl hydrogen bonding results in the formation of a three-dimensional supramolecular network
