Upon treatment of trans-[OsX4(CO)2]− or [OsX5(CO)]2− with oxalate in aqueous solution new complexes of the type mer-[OsX3(CO)ox]2− (X Cl, Br, I) are formed. The IR and Ra spectra are assigned according to point group Cs. In the UV/VIS spectra, recorded at 10 K, charge transfer transitions from ligand levels, splitted by spin-orbit coupling, (π + σ)t1u(X) and πt2u(X) to t2g(Os3+) are observed. Two
