Abstract:
The title compound, [Rh(C(15)H(16)PS)(C(18)H(15)P)(CO)], was synthesized from the reaction of the ligand rac-[Ph(2)PCH(2)CH(CH(3))SH] with trans-[Rh(F)(CO)(PPh(3))(2)] in a 1:1 molar ratio in toluene. The Rh atom is four-coordinated in a distorted square-planar geometry with the P-S ligand [Ph(2)PCH(2)CH(CH(3))S] acting as a chelate and the PPh(3) and disordered CO [site occupation factors of 0.61 (5) and 0.39 (5)] ligands completing the coordination.

Radicals: Electronic Structure and Geometry
Accordingly, the structure of a trivalent radical lies between the geometries of carbocations and carbanions. An sp2-hybridized carbocation is trigonal planar, while an sp3-hybridized carbanion is trigonal pyramidal. Here, the difference in geometry is...
