HYDRIDO-COMPLEXES OF RHODIUM(I) AND COBALT(I)
Abstract
The preparation and properties of complex salts of rhodium(I), of formula (Rh(C2H4(PPh2)2)2) X (X = Cl, ClO4, BPh4), are described. From these a very stable hydrido-complex of rhodium(I), of formula (RhH(C2H4(PPh2)2)2) is prepared by reduction with lithium aluminium hydride and with sodium borohydride. The product of reaction between CoBr2(C2H4(PPh2)2)2 and sodium borohydride, previously described as a derivative of cobalt(O), is shown to be a hydrido-complex of cobalt(I), of formula (CoH(C2H4(PPh2)2)2). This formula is proved by the diamagnetism of the compound, by its infrared spectrum and by its reaction with carbon tetrachloride to give chloroform. The dipole moments, of the order of 3 - 4 D, suggest a non-ortogonal structure for these hydrido- complexes of rhodium and cobalt.
