Abstract
Monosaccharide (D-Glc, D-Fru, D-Gal, D-Xyl, and D-Rib) and disaccharid e (Mall complexes of Co(II) were synthesised from nonaqueous solutions using [NEt(4)](2)[CoCl2Br2] or CoCl2 . 6H(2)O and isolated in the sol id state. The purified complexes were characterized by diffuse reflect ance, 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 tho se synthesised from CoCl2 . 6H(2)O were found to be di- or tetra-nucle ar. 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 Elsevi er Science Ltd.
