A new series of Adducts of Bis(S-isopropyltrithiocarbonato)oxovanadium(IV) with nitrogen and oxygen donor ligands have been prepared. The resulting adducts have been characterized by elemental analysis, molar conductance, magnetic susceptibility measurement, thermal gravimetric analysis, biological studies, IR, UVvisible spectral studies. Analytical data reveals that VO(IV) complexes forms 1:1 adducts. Antifungal activity of some adducts have been carried out against the fungal strain Sclerotium rolfsii. Electronic and magnetic measurements indicate distorted octahedral geometry for the 1:1 adducts of VO(IV) adducts.
