Transition Metal Dialkyldithiocarbamates and Their Antifungal Activity

Abstract

Transition metal dialkyldithiocarbamates [ { (R₂NCS₂)_nM};
R₂ = Me₂ or Et₂ and M = V, Mo, W and Pt] complexes were
prepared by the reaction of metal chloride {MCl_n; n = 3, M = V, W
and n = 4, M = Mo, Pt} with sodium dialkyldithiocarbamate,
[{ R₂NCS₂Na} ; R₂ = Me₂ or Et₂] in dichloromethane/water (1 : 1)
mixture. The metal complexes were characterized by elemental
analysis, solubility, conductance and infrared spectral studies. The
various synthesized complexes along with their parent salts were
screened for their fungitoxicity under in vitro conditions against the
three phytopathogenic fungi viz. Alternaria alternata, Fusarium
oxysporum and Colletotrichum capsici by spore germination inhibition
technique. All the complexes exhibit antifungal activity to
varying extents.
