catena-Poly[[bis-(O,O'-diisopropyl dithio-phosphato-κS,S')nickel(II)]-μ-bis-(4-pyridylmethyl-ene)diazane-κN:N'].

The Ni atom in the title linear supra-molecular polymer, [Ni(C(6)H(14)O(2)PS(2))(2)(C(12)H(10)N(4))](n), exists within a trans-N(2)S(4) octa-hedral donor set defined by two symmetrically coordinating dithio-phosphate ligands and pyridine N atoms derived from two bridging bis-(4-pyridylmethyl-ene)diazane ligands. The Ni atom lies on a centre of inversion and the bis-(4-pyridylmethyl-ene)diazane ligand is also disposed about a centre of inversion. The chains are arranged into layers sustained by C-H⋯S contacts and inter-digitate with neighbouring layers, forming the crystal structure.
