Bis[(4-bromo-2-fluorobenzyl)triphenylphosphonium] bis(1,2-dicyanoethene-1,2-dithiolato)nickelate(II)

M.-G. Liu and C.-L. Ni

Abstract: In the asymmetric unit of the title ion-pair complex, (C₂₅H₂₀BrFP)₂[Ni(C₄N₂S₂)₂], there is one 4-bromo-2-fluorobenzyl)triphenylphosphonium cation, (BrFBzTPP)⁺, and one-half of an [Ni(mnt)₂]^2- anion (mnt is maleonitriledithiolate), which lies on an inversion site. The Ni^II ion is coordinated by four S atoms of two mnt^2- ligands in a square-planar geometry. The (BrFBzTPP)⁺ cation adopts a tetrahedral configuration about P. The cations and anions are linked by weak C-HN and C-HS interactions.
