Treatment of [CuCl(PPh3)] with [NEt4][Rh(cod)(eta5-7,8-C2B9H9Me2)] (Cod = cyclo-octa-1,5-diene) in CH2Cl2 in the presence of TlBF4 affords the dimetal compound [RhCu(PPh3)(Cod)(eta5-7,8-C2B9H9Me2)], the structure of which has been established by X-ray diffraction (Rh-Cu 2.633(2) angstrom, Rb-Cu-P 153.3(1)-degrees). Reactions between [MnBr(CO)5] and the tetraethylammonium salts of the complexes [Rh(CO)(PPh3)(eta5-7,8-C2B9H9Me2)]- and [Rh(cod)(eta5-7,8-C2B9H9Me2)]- yield the dimetal compounds [MnRh(CO)5(L)(eta5 -7,8-C2B9H9Me2)] (L=PPh3 or CO) respectively. Treatment of [Mn(CO)2(NO)(eta5-C5H4Me)][BF4] with INEt4][Rh(CO)(PPh3)(eta5-7,8-C2B9H9Me2)] affords [Rh(NO)(PPh3)(eta5-7,8-C2B9H9Me2)], in an unusual reaction involving transfer of the NO ligand from manganese to rhodium.
