The reactions of the complex (eta-9-Me2S-7,8-C2B9H10)Rh(eta-cod) (cod is 1,
5-cyclo-octadiene) with HX acids (X = Cl, Pr, or I) in acetone afforded rho
dacarborane halide complexes [(eta-9-Me2S-7,8-C2B9H10)RhX2](2) Which are ca
rborane analogs of cyclopentadienyl halide rhodium complexes [(eta-C5R5)RhX
2](2).
