Synthesis and characterization of adducts of Bis(o-isobutyldithiocarbonato) oxovanadium(IV) with substituted pyridines and their biological studies

Abstract

A series of adducts of Bis(O-isobutyldithiocarbonato)oxovanadium(IV) with substituted pyridines have been synthesized by treating Bis(O-isobutyldithiocarbonato)oxovanadium(IV) with substituted pyridines in acetone in equimolar ratios. Analytical results show that the adducts have 1:1 stoichiometry with general formula VO(Oisobulyldithiocarbonato) 2L where L = 2 and 3-bromopyridine; 4-acetylpyridine; 3-hydroxypyridine; 2– methoxypyridine; 2-amino-3-methylpyridine; 2-amino-4-methylpyridine; 2-amino-5-methylpyridine). The addition complexes have been characterized by elemental analysis, conductivity measurements, magnetic susceptibility measurements, infrared and electronic spectral studies. These studies suggest a distorted octahedral structure and paramagnetic nature of the adducts. Antifungal activity of some adducts have been carried out against the fungal strain Sclerotium rolfsii.
