| Abstract: | Reaction of PdPtCl2(dppm)2 with Co(CO)4? or Mn(CO)5? affords the tetrametallic clusters PdPtCo2(CO)7(dppm)2 and PdPtMn2(CO)9(dppm)2. The cobalt cluster reacts with iodide to give PdPtCoI(CO)3(dppm)2 which upon reaction with Fe(CO)3NO? or Mn(CO)5? yields PdPtFeCo(CO)6NO(dppm)2 and PdPtMnCo(CO)8(dppm)2, respectively. |
