The complexes [Mo(
5-C5H5)(CO)2(L)I] (L = P(OMe)3, P(OEt)3, P(OiPr)3, P(OiBu)3,P(OnPn)3) were prepared and characterized by X-ray crystallography. Crystallographic cone(
C) and solid (
C) angles for the phosphite ligands were calculated from the ligandconformations in the crystal structures and compared with the available literature data.The steric data are shown to be influenced by the surrounding ligand environment. Theeffects of the ligand conformation on the steric measurements are discussed, and the resultsapplied to the analysis of equilibrium cis-trans isomer ratios in [Mo(5-C5H5)(CO)2(L)I].
