N2 - Two novel mixed metal rhodium-platinum clusters have been synthesized by the reaction of [Rh4(CO)12] with [Pt(PPh3)3]. The structure of [Rh2Pt3(μ-CO)5(CO)4(PPh 3)3] 1 has been established by a single crystal X-ray diffraction study. The tetranuclear cluster [Rh2Pt2(μ-CO)3(CO)4(PPh 3)3] 2 has been characterised by FAB mass spectrometry and shown by various multinuclear NMR techniques (13C, 31P, {31P-31P} COSY and {13C-103Rh} and {31P-103Rh} heteronuclear multiple quantum coherence, HMQC) to adopt a butterfly type structure. The carbonyl migration pathways in 2 have been established by a combination of EXSY and 1-D variable temperature measurements; independent localised exchange about the hinge rhodium atoms and interchange of bridging and semi-bridging carbonyls on the Pt-Rh bonds occur.
