Abstract
The interactions of oxotitanium(IV) and oxovanadium(IV) with arylbis ( 5-hydroxy-3-methyl-1-phenyl-4-pyrazolyl)methane (ArBPyM) ligands conta ining enolic oxygen donors, have been studied with ir spectroscopy, th ermogravimetric measurements and elemental analysis. The results indic ate the probable formation of dimeric complexes (metal : ligand ratio = 1:1) through bridging sulfato ligand. Application of differential th ermal analysis allowed determination of the mechanism of thermal decom position of the complexes.
