A. M. Hardy and R. L. LaDuca

Abstract: 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-HCl interactions to form supramolecular layers, which in turn stack to construct the three-dimensional crystal structure.
