The iodide induced dimerisation of a 
 dppm-/diphenylphosphido-bridged Pt22+ system leads to 
 a 56 CVE Pt4 butterfly cluster which is diprotonated by 
 HO3SCF3 to give a 60 CVE rectangular Pt4 
 cluster.
                                    dppm-/diphenylphosphido-bridged Pt22+ 系统在
碘化物的诱导下发生二聚反应,生成 56 CVE 的 Pt4 蝶形簇,该簇在 HO3SCF3 的作用下发生二质子化反应,生成 60 CVE 的矩形 Pt4 簇。
