Abstract
Rhodium complexes in which two azoarene groups act as chelating ligands have been obtained both from rhodium trichloride and from rhodium carbonyl chloride and shown to yield bis(arylazo)biphenyls on carbonylation; the structure of the mononuclear bis(azoarene)rhodium acetate has been established by X-ray crystallography.
