Název v původním jazyce

Tetramethyl(perfluoroalkyl)cyclopentadienyl rhodium(III)complexes containing phosphorus and nitrogen monodentate donors. Crystal structure of [(5-C5Me4C4F9)Rh(PPri3)Cl2]

Popis výsledku v původním jazyce

Cleavage of a double &#61549;-halo bridge in complexes [(C5Me4CnF2n+1)RhX2]2 (n = 4, 6; X = Cl, Br) with two-electron monodentate Pdonors like phosphines or phosphites or monodenate N-donors like pyridine-derived heterocyclic amines gave mononuclear Rh(III) complexes of piano-stool type [(C5Me4CnF2n+1)RhX2L] (L = two-electron donor). Crystal structure of [(&#61544;5-C5Me4C4F9)Rh(PPri3)Cl2] was determined by X-ray diffraction. The compound had a pseudo-tetrahedral ligand arrangement around the Rh atom. The perfluoroalkyl chain was averted from the phosphine ligand but not completely; after projection to the ring plane the P? (ring centroid) ? CF2 angle was around 166°. In contrast to their Cp* analogs, the pyridine complexes were stable in solution at room temperature. Free rotation of triarylphosphine ligands around Rh?P bond and 2-substituted pyridine ligands around Rh?N bond was hindered, giving the values of &#61508;G++ = 14.8 ? 0.1 kcal mol-1 at 27°C and &#61508;G++ = 14.9 ?
