Bis(tetra­phenyl­phospho­nium) bis­[N-(phenyl­sulfon­yl)dithio­carbimato-κ(2) S,S′]platinate(II) monohydrate

The asymmetric unit of the title compound, (C(24)H(20)P)(2)[Pt(C(7)H(5)NO(2)S(3))(2)]·H(2)O, consists of two tetra­phenyl­phospho­nium cations, two half bis­[N-(phenyl­sulfon­yl)dithio­carbim­ato]platinate(II) dianions and one water mol­ecule. The anions are completed by crystallographic inversion symmetry associated with the central Pt(II) ion. The Pt(II) ion is doubly S,S′-chelated by two symmetry-related phenyl­sulfonyl­dithio­carbimate ligands, forming a slightly distorted square-planar configuration. Besides the electrostatic attraction between oppositely charged ions in the crystal packing, intra­molecular C—H⋯O and several inter­molecular C—H⋯O, C—H⋯N and O—H⋯O hydrogen-bonding inter­actions between the cations, anions and water mol­ecules are observed.
