Abstract

Two new complexes having general formula VOL· nHO [( 1) L: 5-hydroxyflavone, n = 1; ( 2) L: chrysin, n = 4] were synthesized and characterized. Based on IR and electronic data we concluded that studied flavones act as bidentate ligands in complexes with metallic ion coordinated in a square-pyramidal stereochemistry. The thermal analysis (TG, DTA) elucidated the composition and also the number and nature of the water molecules. The thermal behavior also indicated strong interactions between oxovanadium (IV) and these oxygen donor ligands. [ABSTRACT FROM AUTHOR]
