[PtCl2(NCBut)2] or [PtCl2(cyclo-1,5-octadiene)] with Ph2P(CH2)n P(O)Ph2 (n = 1, dppmO; n = 2, dppeO; n = 3, dpppO; n = 4, dppbO) gives complexes of the type cis-[PtCl2Ph2P(CH2)nP(O)Ph2}2], independently of mole ratio. Treatment of cis-[PtCl2(dppmO)2] with LiBr or NaI gives [PtX2(dppmO)2] (X = Br, cis; X = I, cis/trans mixture) and on treatment with Hg(CCPh)2 in ethanol, trans-[Pt(CCPh)2(dppmO)2] is formed
