Reactions of rhodium carbonyl clusters with heterobidentate ligands. Synthesis and structural characterization of the Rh6(CO)15[(C6H5)2PC6H4N(CH3)2] and {Rh6(CO)15[(C6H5)2PC6H4NH(CH3)2]}[GaX4] cluster compounds

Abstract

The reaction of heterobidentate 4-(dimethylamino)phenyldiphenylphosphine with labile cluster Rh6(CO)15(NCMe) yielding a new monosubstituted cluster Rh6(CO)15(Ph2PC6H4NMe2) was described. The reactions of the resulting cluster with GaX3 compounds were studied. The structure of all obtained compounds was completely characterized both in a solid phase and in a solution by X-ray diffraction analysis, mass spectrometry, and IR and polynuclear NMR spectroscopy.
