catena-Poly[[dichloridozinc(II)]-μ-1,4-bis(3-pyridylmethyl)piperazine]

In the title compound, [ZnCl2(C16H20N4)]n, tetrahedrally coordinated divalent Zn atoms are ligated by two Cl atoms and two N-donor atoms from two 1,4-bis(3-pyridylmethyl)piperazine (3-bpmp) ligands. The tethering 3-bpmp ligands promote the formation of [ZnCl2(3-bpmp)]n chains situated parallel to (overline{1}02). These chains aggregate via C—H...Cl interactions to form supramolecular layers, which in turn stack to construct the three-dimensional crystal structure.
