title: Bis[(2-chloro-4-fluoro-benz-yl)triphenyl-phospho-nium] bis-(1,2,5-thia-diazole-3,4-dithiol-ato)nickelate(II).
abstract: The title ion-pair complex, (C(25)H(20)ClFP)(2)[Ni(C(2)N(2)S(3))(2)], was obtained by the direct reaction of (4-F,2-ClBzTPP)(+)·Br(-) [4-F,2-ClBzTPP(+) is (2-chloro-4-fluoro-benz-yl)triphenyl-phos-pho-nium], NiCl(2)·6H(2)O and Na(2)tdas (tdas(2-) is 1,2,5-thia-diazole-3,4-dithiol-ate) 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 Ni(II) ion situated on a center of symmetry, leading to a slightly distorted square-planar coordination of the latter. In the cation, the tetra-hedral 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.
