TRANSITION-METAL SACCHARIDE CHEMISTRY AND BIOLOGY - SYNTHESIS, CHARACTERIZATION, REDOX BEHAVIOR, BIOINTERACTION AND DATA CORRELATIONS OF DINUCLEAR CHROMIUM(III) COMPLEXES

A series of dinuclear chromium(III) complexes has been synthesised by reduction of chromate by a variety of saccharides and related compound s. The complexes have been characterised by various analytical (elemen tal and ICP-AES analysis, TLC, HPLC) and spectroscopic (UV/VIS, FTIR, EPR, H-1 and C-13 NMR) methods. Antiferromagnetic interactions between the two Cr-III centres have been established by magnetic susceptibili ty measurements and the hydrolytic stability and redox behaviour of th e complexes have been established by extensive electrochemical studies which gave several correlations. The interaction of some of the compl exes with DNA has been studied by gel electrophoresis.
