catena-Poly[[bis(O,O'-diisopropyl dithiophosphato-²S,S')nickel(II)]--bis(4-pyridylmethylene)diazane-²N:N']

E. Berdugo and E. R. T. Tiekink

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-HS contacts and interdigitate with neighbouring layers, forming the crystal structure.
