Synthesis and Characterization of Oxotitanium(IV) and Oxovanadium(IV) Complexes of Arylbis(5-hydroxy-3-methyl-1-phenyl-4-pyrazolyl)methane Ligands

Abstract

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