Crystal and molecular structure of trans-[RhCl(CO)(P t Bu2Ph)2]

Abstract

Abstract Treatment of THF solutions containing the rhodium(II) complex trans-[RhCl2(P t Bu2Ph)2] (1) with [Fe2(CO)9] in the same solvent resulted in the formation of the Vaska-type complex trans-[RhCl(CO)(P t Bu2Ph)2] (2) in high yield. The title complex 2 was obtained as pale yellow crystals, characterized by NMR and IR spectroscopy, as well as by microanalyses. Additionally, the molecular structure of 2 has been established by X-ray crystallography. As often reported for similar constituted compounds, the chlorido and carbonyl ligands in crystals of 2 are strongly disordered.
