Synthesis and structural characterization of manganese(II), cobalt(II) and zinc(II) complexes of isonitrosoacetophenone thiosemicarbazone and isonitroso-4-chloroacetophenone thiosemicarbazone

Abstract

The complexes of the formulae [MLCl₃]Cl, [MLCl₃]Cl (M = Ti); ML₂ {where M = Mn(II), Co(II), Ni(II) and Zn(II); L = isonitrosoacetophenone thiosemicarbazone (INAPT) and L' = isonitroso-4- chloroacetophenone thiosemicarbazone] have been prepared and characterized on the basis of elemental analysis, conductance, magnetic moments, IR, electronic and NMR spectral data. In all the complexes the ligand is coordinated to the central metal ion through 'S' (>C = S) 'N' (N - OH) after deprotonation and 'N' (C= N) as shown by IR and NMR spectral studies.
