Abstract: In the title dinuclear rhodium complex, [(-C₂O₄){(⁵-C₅Me₅)Rh(O₃SCF₃)}₂] or [Rh(CF₃O₃S)₂(C₁₀H₁₅)₂(C₂O₄)], the terminal trifluoromethanesulfonate ligands adopt a trans configuration with respect to each other and the RhRh distances range from 5.5157 (8) to 5.5389 (6) Å. There are two and a half molecules within the asymmetric unit, one of the molecules lying on an inversion centre. Interestingly, in one molecule, the S-O bond of a coordinated O atom is shorter than the two S-O bonds of the noncoordinated O atoms, and the corresponding Rh-O distance is significantly longer than the other M-O distances.
