The following four chromium(III) and cobalt(III) double complexes were prepared and the thermal reactions were investigated both isothermally and non-isothermally in the solid-phase: [(Cr or Co)(H<SUB>2</SUB>O)(NH<SUB>3</SUB>)<SUB>5</SUB>][(Cr or Co)(sida)<SUB>2</SUB>] where sida denotes <I>N</I>-(2-sulfoethyl)iminodiacetate ion. The double complexes were found to be thermally deaquated to form the homo- and hetero-metal binuclear complexes [(NH<SUB>3</SUB>)<SUB>5</SUB>(Cr or Co) (sida)(Cr or Co)sida)] in which one of <I>N</I>-(2-sulfoethyl)iminodiacetate ions functions as the bridging ligand between two metal ions. The complexes thus obtained were purified from a 50% HClO<SUB>4</SUB> or a 1 M NaClO<SUB>4</SUB> solution in the forms of the hydrogen salts [(NH<SUB>3</SUB>)<SUB>5</SUB>(Cr or Co)(sida) (Cr or Co)(sidaH)]ClO<SUB>4</SUB> or the sodium salts [(NH<SUB>3</SUB>)<SUB>5</SUB>(Cr or Co)(sida)(Cr or Co)(sidaNa)]ClO<SUB>4</SUB>.
