Popis:	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)(H2O)(NH3)5][(Cr or Co)(sida)2] where sida denotes N-(2-sulfoethyl)iminodiacetate ion. The double complexes were found to be thermally deaquated to form the homo- and hetero-metal binuclear complexes [(NH3)5(Cr or Co) (sida)(Cr or Co)sida)] in which one of N-(2-sulfoethyl)iminodiacetate ions functions as the bridging ligand between two metal ions. The complexes thus obtained were purified from a 50% HClO4 or a 1 M NaClO4 solution in the forms of the hydrogen salts [(NH3)5(Cr or Co)(sida) (Cr or Co)(sidaH)]ClO4 or the sodium salts [(NH3)5(Cr or Co)(sida)(Cr or Co)(sidaNa)]ClO4.
