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 (02). These chains aggregate via C—H⋯Cl interactions to form supramolecular layers, which in turn stack to construct the three-dimensional crystal structure.
The structure was refined from a merohedrally twinned crystal; for the generation of reflection data from the major twin component, see: Sheldrick (2007 ▶). For 1,4-bis(3-pyridylmethyl)piperazine coordination polymers of copper arylcarboxylates, see: Johnston et al. (2008 ▶). For the synthesis of the ligand, see: Pocic et al. (2005 ▶).
