Abstract
A series of adducts of bis(O-isopropyldithiocarbonato)oxovanadium(IV) with substituted pyridines have been synthesized by treating bis(O-isopropyldithiocarbonato)oxovanadium(IV) with substituted pyridines in acetone in equimolar ratios. Analytical results show that the adducts have 1:1 stoichiometry with general formula VO(O-isopropyldithiocarbonato)2L where L = 2 and 3-bromopyridine; 4-acetylpyridine; 3-hydroxypyridine; 2-methoxypyridine; 2-amino-3-methylpyridine; 2-amino-4-methylpyridine; 2-amino-6-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. Xanthate have recently been shown to inhibit the replication of both DNA and RNA viruses in vitro. It was found that certain xanthate derivatives exhibit beneficial antimicrobial and antiviral effects 7 . Here we report synthesis and investigation of the 1:1 adducts of some adducts of oxovanadium(IV)xanthates with substituted pyridines such as 2 and 3-bromopyridine; 4-acetylpyridine; 3-hydroxypyridine; 2-methoxypyridine; 2-amino-3- methylpyridine; 2-amino-4-methylpyridine and 2-amino-6-methylpyridine.
