Sulfitoamine Complexes of Cobalt(III)

Abstract Monosulfito and bis(hydrogensulfito) cobalt(III) complexes were prepared using sodium sulfite and sodium metabisulfite salts respectively. The two types of products showed different and characterizing patterns of IR and UV-visible spectra. They both contain Co-SO3 linkages and the sulfite groups have similar or different site symmetries in the same compound.
