Mayer, Peter; Boettcher, Hans-Christian (2018): Crystal and molecular structure of trans-[RhCl(CO)((PBu2Ph)-Bu-t)(2)]. In: Zeitschrift für Naturforschung Section B-A Journal of Chemical Sciences, Vol. 73, No. 12: pp. 1029-1032
Full text not available from 'Open Access LMU'.


Treatment of THF solutions containing the rhodium(II) complex trans-[RhCl2(Mu(2)Ph)(2)] (1) with [Fe-2(Co)(9)] in the same solvent resulted in the formation of the Vaska-type complex trans-[RhCl(CO)((PBu2Ph)-Bu-t)(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.
