Description Monosaccharide (D-Glc, D-Fru, D-Gal, D-Xyl, and D-Rib) and disaccharide (Mall complexes of Co(II) were synthesised from nonaqueous solutions using [NEt(4)](2)[CoCl2Br2] or CoCl2 . 6H(2)O and isolated in the solid state. The purified complexes were characterized by diffuse reflectance, aqueous solution absorbance, CD, FTIR, magnetic susceptibility, EPR, and cyclic voltammetric studies. The complexes synthesised from [NEt(4)](2)[CoCl2Br2] were found to be primarily dinuclear, whereas those synthesised from CoCl2 . 6H(2)O were found to be di- or tetra-nuclear. The hydrolytic stability of the complexes followed a trend: D-Rib > Mal > D-Glc > D-Xyl > D-Fru much greater than D-Gal. (C) 1997 .
