Cyano- and cyanohydrido-complexes of rhodium

Abstract

The preparation of dipotassium 1-hydrido-6-aquotetracyanorhodate (III), K2[RhH(CN)4(H2O)], from rhodium carbonyl chloride is described. A polymeric cyanocarbonyl of rhodium, [Rh(CO)2CN]n is formed as a stable intermediate in this preparation. The hydrido-complex reacts with oxygen, nitric oxide, and tetrafluorethylene, and the resulting complexes have been characterised as, respectively, K4[(CN)4(H2O)RhO2Rh(CN)4(H2O)], K2[Rh(CN)4NO2(H2O)], and K3[Rh(CN)5C2F4H].

The fusion of rhodium(III) chloride hydrate with potassium cyanide yields a rhodium(I) species which is oxidised by water to a hydridocyano-anion.
