Synthesis and Structural Aspect of Some Transition Metal Complexes with Schiff Base Ligand Derived from 2, 6 Diethyl 4-pyrone

摘要

A series of transition metal complexes of Co(II), Ni(II) and Cu(II) having the general composition [M(DEPS)2X2]; where, M = Co(II), Ni(II) and Cu(II), DEPS = 2, 6 Diethyl 4-pyrone semicarbazone, X = CI~-, Br, I~- and NO_3~- have been prepared. The prepared complexes were characterized by elemental analyses, molar conductance, magnetic susceptibility measurements, IR and electronic spectral studies. From the perusal of IR spectral data, it is proposed that the Schiff base DEPS behaves as a bidentate ligand and coordination proposes through azomethine N and carbonyl oxygen atom of semicarbazone moiety. The remaining positions of metal ions are satisfied by negative ions, such as CI~-, Br, I~- and NO_3~-. Electronic, spectral data and magnetic susceptibility measurement indicate octahedral geometry around central metal ion.
