Synthesis of Transition Metal Diethyldithiocarbamates and Their Effect on Nodulation and Other Growth Characters in Mungbean, Vigna radiata

Abstract

The present investigation involves the synthesis of some metal
diethyldilbiocarbamates and their effect on symbiotic activity of
mungbean. Metal diethyldithiocamates, [(C₂H₅)₂NCS₂]_nM
(M = Zn,  Mn,  Cd), were synthesized by the reaction of metal chloride
with sodium diethyldithiocarbamate in dichloromethane/water
mixture. The metaI-complexes were soluble in chloroform, carbon
tetrachloride, telrahydrofuran and benzene. The dithiocarbamate
ligand acted as bidentate in all the metal-complexes. The metaI-complexes
were  screened for theit effect on growth characters and
symbiotic activity of mungbean, Vigna radiata ML 267  at various
concentrations. The complexes of zinc and manganese significantly
increased the dry weight of root and shoot, number of nodules, dry,
weight of nodules and chlorophyll content of leaves.
