Abstract
Mer-[Rh(DMSO)2(DMF)Cl3] was prepared by dissolving [Rh(DMSO)3Cl3] in dimethylformamide (DMF). It forms monoclinic crystals, a = 11.530(3), b = 8.971(2), c = 15.912(3) Å, β = 107.88(2)°, Z = 4, and space group P21/c. The structure was refined by full-matrix least-squares analysis to a conventional R factor of 0.038 (3495 observed reflections).The coordination around the Rh atom is octahedral. The compound is the peripheral or the 1,2,6-isomer. The DMF molecule is in trans position to a DMSO ligand and bonded to rhodium through the oxygen atom. The two molecules of DMSO are bonded to rhodium through sulfur. The Rh—Cl(1) bond (2.366(1) Å) trans to a DMSO molecule seems slightly longer than the two Rh—Cl bonds trans to each other (2.329(1) and 2.343(1) Å).Keywords
