Abstract

The dirhodium complex, [Rh(2)(C(18)H(15)P)(4)(CO)(2)]·2(CH(3))(2)CO, has crystallographic twofold symmetry and the Rh-Rh distance is 2.6266 (8) Å. The four atoms proximate to each Rh atom [Rh-P = 2.3222 (7) and 2.3283 (8) Å, and Rh-C = 1.961 (3) and 2.045 (3) Å] form a distorted tetra-hedron with large deviations from the putative tetra-hedral angles [r.m.s. deviation = 23 (1)°]. The six angles more closely approximate those of a trigonal bipyramid [r.m.s. deviation = 14 (1)°] with one missing equatorial ligand. The two bridging carbonyl ligands are much more linearly coordinated to one Rh [Rh-C O = 151.0 (2)°] than to the other [127.0 (2)°], and the two Rh(2)CO planes form a dihedral angle of 45.43 (5)°. The two acetone solvent mol-ecules are disordered, and their estimated scattering contribution was subtracted from the observed diffraction data using the SQUEEZE routine in PLATON [Spek (2009 ▶). Acta Cryst.D65, 148-155].
