Crystal structures of the final product, fac-[Rh(Ph2PCH2CO2)3]·PhNO2·H2O, and of the key intermediate, mer-[RhCl(H)(Ph2PCH2CO2)(Ph2PCH2CO2H)2]·C4H8O, were determined. The latter structure is unique in that it contains both hydride and a carboxylic proton in one molecule.

Whole blood was precipitated with zinc sulphate, extracted with diethyl ether, evaporated, dissolved in aqueous methanol and partitioned twice with n-hexane. Chromatography was carried out using a microbore RP-column under isocratic elution with acetonitrile–methanol–water (200:80:140,
