Two novel heterometallic octahedral clusters [Rh4Pt 2(CO)11,(dppm)2] (1) and [Ru2Rh 2Pt2(CO)12(dppm)] (2) were synthesized by the reaction of [Rh2Pt2(CO)6(dppm)2] with [Rh6(CO)14(NCMe)2] and Ru 3(CO)12, respectively. Solid state structures of 1 and 2 have been established by a single crystal X-ray diffraction study. Two dppm ligands in 1 are bonded to one platinum and three rhodium atoms, which form an equatorial plane of the Rh4Pt2 octahedron. Two rhodium and two platinum atoms bound to the diphosphine ligands in 2 are nonplanar to give an octahedral C2 symmetric Ru2Rh2Pt 2(dppm)2 framework. The 31P NMR investigation of 1 and 2 (ID, 31P COSY, 31P-{103Rh} HMQC) and simulation of 1D spectral patterns showed that in both clusters the structures of the M6(PP)2 fragments found in the solid state are maintained in solution.
