PREPARATION AND PROPERTIES OF VANADYL(IV)SACCHARINATE

The synthesis of a new vanadyl(IV)/saccharin complex is reported. Its bonding characteristics differ considerably from all known divalent me tal-saccharinates. In this complex a VO(OH)+ moiety is coordinated to a saccharin molecule through its carbonyl oxygen and to a saccharinate ion through its deprotonated nitrogen. Two water molecules complete t he coordination sphere. X-ray powder diagrams, infrared- and electroni c absorption-spectra were recorded and analyzed for the characterizati on of the compound and its coordination properties. Besides, the magne tic susceptibility and the thermal behaviour were also investigated.
