ABSTRACT: Some new first row transition metal complexes of types ML2 {M=Mn(II), Co(II), Ni(II), Cu(II) and Zn(II)} and M'L3 {M'=Cr(III) and Fe(III)} with dithiocarbamate ligand derived from 4-amino-3, 5-bis(pyridine-2-yl)-1,2,4-triazole have been prepared by the replacement reaction. These complexes have been characterized by elemental analysis, conductivity measurements and infrared spectral studies. All the complexes were non-electrolyte in nature. Infrared spectral data of these complexes showed the bidentate behaviour of ligand and metals were found to be tetra and hexa-coordinated in ML2 and M'L3 type of complexes respectively.
