Bis(benzyltriphenylphosphonium) bis(1,2-dicyanoethene-1,2-dithiolato)nickel(II)

J.-R. Zhou, C.-L. Ni and L.-L. Yu

Abstract: The asymmetric unit of the title compound, (C₂₅H₂₂P)₂-[Ni(C₄N₂S₂)₂] or (BzTPP)₂[Ni(mnt)₂] (where BzTPP is 1-benzyltriphenylphosphonium and mnt is maleonitriledithiolate), consists of one (BzTPP)⁺ cation and one-half of a centrosymmetric [Ni(mnt)₂]^2- anion. The Ni^II atom of the anion is coordinated by four S atoms from two mnt^2- ligands and exhibits the expected square-planar coordination geometry. The (BzTPP)⁺ cation adopts a conformation where the four phenyl rings are twisted with respect to the plane of the P-C-C chain that links them. Weak C-HN and C-H [pi] interactions are present in the crystal structure.
