trans-Carbonyl-chloridobis[tris-(4-chloro-phen-yl)phosphane]rhodium(I) acetone monosolvate.

The title compound, trans-[RhCl(C(18)H(12)Cl(3)P)(2)(CO)]·C(3)H(6)O, contains an Rh(I) atom in a distorted square-planar coordination with a P-Rh-P angle of 175.27†(2)° and Rh-P bond lengths of 2.3127†(4) and 2.3219†(4)†à . The rhodium complexes link each other through weak inter-molecular contacts between the acetone methyl groups and the carbonyl O atom. Inter-actions between the acetone solvent mol-ecule and the Cl-Rh unit results in a reduced P-Rh-Cl angle of 86.675†(15)°.
