excellent yield. The salts and neutral complexes can be interconverted, e.g. the nitrate salt with NaI gives the neutral platinum–silver iodide complex and when the neutral platinum–silver chloride complex [(PhCC)2Pt(µ-dppm)2AgCl] is treated with [NH4][PF6] in acetone the corresponding [PF6]– salt is formed. A more convenient method of synthesis of the complex [(PhCC)2Pt(µ-dppm)2AgX] is to treat [Pt(dppm-PP′)2]X2(X
