X-Ray structure of the hydrido-tris(triphenylphosphine)-ruthenium(II) ion, [RuH(PPh3)2(η-Ph-PPh2)]+
Abstract
The X-ray crystal structure of hydridotris(triphenylphosphine)ruthenium(II) tetrafloroborate confirms a previous suggestion based on spectroscopic studies that one of the phenyl rings of one triphenylphosphine group is bound as an arene to the metal; 31P n.m.r. spectra are in accord with the structure but unusual dependence of the low field doublet intensity upon the frequency of the secondary irradiating field at proton resonance frequencies is observed.
