catena-Poly[[[bis-(O,O'-diisobutyl dithio-phosphato-κS,S')nickel(II)]-μ-1,2-bis-(4-pyridylmethyl-ene)hydrazine-κN:N'] toluene disolvate]

The polymeric title compound, {[Ni(C(8)H(18)O(2)PS(2))(2)(C(12)H(10)N(4))]·2C(7)H(7)}(n), has a linear topology and features octa-hedrally coordinated Ni atoms with a trans-N(2)S(4) donor set. The toluene solvent mol-ecules occupy channels defined by the three-dimensional stacking of the polymeric chains. The Ni atom is located at a centre of inversion and the bridging 1,2-bis-(4-pyridylmethyl-ene)hydrazine4-pyridine mol-ecule is also disposed about a centre of inversion. One isobutoxy group is disordered equally over two positions.
