Reactions of Rh(N-O)(CO)[P(4-X-C6H4)3][(N-O) = 2-C5NH4COO(pyC) and 2-C9NH6COO (quin), X = CH3O, CH3, F, Cl] with Hg(R)(OOCCF3) (R = Ph, OOCCF3) lead to the hexacoordinate rhodium(III), Rh(HgR)(OOCCF3)(N-O)(CO)[P(4-X-C6H4)3], complexes. The new compounds evolve in solution to the decarbonylated species Rh(R)(OOCCF3)(N-O)(H2O)[P(4-X6-C6H4)3]. The crystal of one of the above derivatives, Rh(OOCCF3)2(quin)(H2O)[P(4-CH3-C6H4)3], is reported, and a distorted octahedral coordination around the rhodium atom with the two monodentate OOCCF3 ligands in cis positions is found.
