Synthesis, characterization and antifungal properties of some nickel(II), copper(II), zinc(II) and cadmium(II) complexes N-methyl-S-benzyldithiocarbazate

Abstract

Complexes of general formula, M(N-SBz)₂X₂ [M= Ni(II), Cu(II), X = NO₃, 0.5 SO₄; M= Cd(II), X= NO₃, 0.5 SO₄; and M(N-SBz)X₂ [M= Cu(II), X = Cl, Br; M = Cd(II), X = Cl; N-SBz = N-methyl-S-benzyldithiocarbazate] have been synthesized and characterized by magnetic and spectroscopic methods. The copper[II] complexes, Cu(N-SBz)X₂ have room-temperature magnetic moments of 1.78-1.81 B.M. Electronic and ESR spectroscopic data support polymeric tetra-gonal structures for these complexes. Some of complexes have been tested for their antifungal activities against three pathogenic fungi, <em>viz</em>. <em>Alternaria solani</em>, <em>Curvularia geniaculata</em> and <em>Colletotrichum capsici</em>.
