Complexes triamminés du rhodium(III) I. Un nouveau complexe du rhodium(III): La rhodium(III)-trihydroxo-triammine préparation, identification et étude de quelques unes de ses propriétés physico-chimiques

Arrangement of Rh3+ions infac-triamminetrichloridorhodium from powder data and infac-triamminetrinitratorhodium crystals twinned by merohedry

“…Since the publication of the first work on the synthesis of triamminetrichloridorhodium(III) (Lebedinskij, 1935) there have been reports of the syntheses of only three related complexes, viz. Rh(NO 2 ) 3 (NH 3 ) 3 (Lebedinskij & Shenderetskaya, 1940), Rh(OH) 3 (NH 3 ) 3 and RhCl 3 (NH 3 ) 3 (Pannetier et al, 1969). The absence of reports on the synthesis and study of the properties of this triammine series of complexes with other acido ligands is surprising because they possess very low solubility and can potentially be used both in processes for refining platinum group metals and in the development of gravimetric methods for the determination of rhodium.…”
