The reaction of [Pt(NSO)2(PMe2Ph)2] with water in dichloromethane gives the compounds [Pt(SO3)(PMe2Ph)3].H2O 1 and [Pt(SO3)(PMe2Ph)2}2].5CHCl3 2 which have been characterised by multielement NMR spectroscopy and X-ray crystallography. The mononuclear compound 1 has tetrahedrally distorted square-planar co-ordination of the platinum by three phosphines and the sulfur atom of the sulfite with trans angles of 160.4(1) and 161.2(1)-degrees. The binuclear complex 2 contains a six-membered Pt2S2O2 ring in a chair conformation with each platinum being co-ordinated by two phosphines and a sulfur and oxygen atom of the different SO3(2-) ligands. Phosphorus-31 NM R studies show that the reaction of Ag2SO3 with [PtCl2(PR3)2] gives 1 and 2 or simple, O,O' complexes depending on the nature of PR3.
