A prolonged storage of a solution of RhCl3?nH2O in N,N-dimethylformamide (DMF) at room temperature is attended by the consecutive formation of two precipitates, which mainly contain the [(CH 3)2NH2][RhCl5(DMF)] complex (I) and the complex [RhCl3(DMF)3] (II) liberates. The addition of PPh4Cl to an aqueous solution of complex I brings about the precipitation of [PPh4][RhCl4(H2O)2] (III). Complex II (a mixture of mer-and fac-isomers) can be obtained also by treatment of [RhCl3(CH3CN)3] with DMF. In the course of the latter reaction, the formation of intermediate complex [RhCl 3(CH3CN)2(DMF)] (IV) is observed. Complexes I-IV are characterized by elemental analysis; complexes I, II, and IV are characterized by the IR and 1H and 13C NMR spectra. The structures of III and IV are determined by X-ray diffraction analysis. Nauka/Interperiodica 2007.
