Bis[(2-chloro-4-fluorobenzyl)triphenylphosphonium] bis(1,2,5-thiadiazole-3,4-dithiolato)nickelate(II)

Abstract

The title ion-pair complex, (C25H20ClFP)2[Ni(C2N2S3)2], was obtained by the direct reaction of (4-F,2-ClBzTPP)+·Br− [4-F,2-ClBzTPP+ is (2-chloro-4-fluoro­benz­yl)triphenyl­phos­pho­nium], NiCl2·6H2O and Na2tdas (tdas2− is 1,2,5-thia­diazole-3,4-dithiol­ate) in methanol. The asymmetric unit of the title structure comprises one (4-F,2-ClBzTPP)+ cation and half of an [Ni(tdas)2]2− complex anion, with the NiII ion situated on a center of symmetry, leading to a slightly distorted square-planar coordination of the latter. In the cation, the tetra­hedral angles around the P atom are nearly undistorted. In the crystal, the cations and anions are linked by C—H⋯S, C—H⋯N and C—H⋯Cl hydrogen bonds.
