[Pt2Me2(µ-Ph2PCH2PPh2)2][Bf4]2, a highly reactive and co-ordinatively unsaturated di-platinum(II) complex. Crystal structures of [Pt2Me2L2(µ-Ph2PCH2PPh2)2][BF4]2, L = MeCN or CO

Abstract

Treatment of [Pt₂Me₃(Ph₂PCH₂PPh₂)₂][BF₄] with Ph₃C⁺BF₄^– in wet CH₂Cl₂ gives [Pt₂Me₂(Ph₂PCH₂PPh₂)₂]²⁺ which reacts rapidly with MeCN, CO, OH^–, Cl^–, or MeOH to give several new complexes or adducts, including ‘A-frames’.
