Syntheses and characterization of trigonal-bipyramidal rhodium(I) complexes of tris(2-(diphenylphosphino)ethyl)phosphine and determination of a spectroscopic trans-influence series by 31P{1H} NMR spectroscopy

A series of low-spin, five-coordinate rhodium(I) complexes of the tripod ligand tris(2-(diphenylphosphino)ethyl)phosphine, PP3, were synthesized and characterized by elemental analyses, infrared spectra, and 31P{1H} NMR spectra. The complexes have trigonal-bipyramidal geometries in which the PP3 ligand occupies four of the five sites of C3v symmetry and the variable fifth ligand is monodentate. The 31P NMR spectral patterns are consistent with AMX3 and AKMX3 spin systems. The NMR spectra permit a determination of the trans influence of the fifth ligand on the rhodium-phosphorus apical coupling constant and the chemical shifts of the apical and equatorial phosphorus atoms of PP3.
