Abstract
Thorium(IV) complexes have been synthesized by reacting Th(IV) nitrate with Schiff bases derived from 2,6-diformyl-4-methyl phenol and 3-substituted-4-amino-5-mercapto-1,2,4-triazoles in ethanol. These complexes have been characterized on the basis of elemental analyses, molar conductance and spectral studies. Analytical and spectral data suggest structures in which Th(IV) is six-coordinate, which is supported by coordination of seven nitrate ions with one bidentate, hydroxyl group of 2,6-diformyl-4-methyl phenol in a bidentate fashion and two azomethine groups through nitrogen atoms. The fluorescence and solid state electrical conductivity properties have been studied.
