Synthesis and characterization of copper(II), nickel(II), cobalt(II), zinc(II) and cadmium(II) complexes of 5,6-diphenyl-3-(2 -hydroxyphenyl)-1, 2, 4-triazine

Abstract

A few complexes of the type ML₂.nB, [where M =Cu(II), Ni(U), Co(ll), Zn(II), Cd(II); L =5,6-diphenyl-3-(2'- hydroxyphenyl)-1, 2, 4-triazine (DPTH); B= H₂O; n = 0, 2] have been synthesized and characterized on the basis of elemental analysis, magnetic susceptibility, thermal studies and IR and electronic spectra. It is observed from the IR studies that the nitrogen in 2-position of DPTH is coordinated to the metal ion in all the cases.
