Synthesis and Characterization of Mn(II), Fe(II), Co(II) and Ni(II) Complexes of Salicyloylpyrazole Oxime

Abstract

In the present investigation, a simple and efficient synthesis of Mn(II), Fe(II), Co(II) and Ni(II) complexes containing salicyloylpyrazole oxime moiety is reported. The synthesized complexes were characterized by elemental analysis and spectral techniques such as IR, NMR and UV-visible. The formation of complexes were also confirmed by thermal studies and molar conductance. The analytical data supports 1:2 stoichiometry for metal:ligand. The molar conductivity data indicated the non-electrolytic nature of complexes. The electronic absorption spectra suggested the square planar geometry for metal complexes.
