Abstract

The Ni atom in the title linear supramolecular polymer, [Ni(C6H14O2PS2)2(C12H10N4)]n, exists within a trans-N2S4 octahedral donor set defined by two symmetrically coordinating dithiophosphate ligands and pyridine N atoms derived from two bridging bis(4-pyridylmethylene)diazane ligands. The Ni atom lies on a centre of inversion and the bis(4-pyridylmethylene)diazane ligand is also disposed about a centre of inversion. The chains are arranged into layers sustained by C—H⋯S contacts and interdigitate with neighbouring layers, forming the crystal structure.
