Synthesis and Characterization of Cu(II), Ni(II) and Co(II) Binuclear Complexes with a new Schiff base (1,3-bis [ortho-(2-carboxy-phenyliminomethyl)-phenoxy] propane)

摘要

A new Schiff base, H2L (C_(31)H_(26)O6N2), was synthesized starting from a dialdehyde [1,3-bis(2'- formylphenyl)-1,3-dioxapropane] and 2-aminobenzoic acid. Corresponding metal complexes with Cu(II), Ni(II) and Co(II) were also prepared. The structure of the Schiff base was characterized using spectroscopic data and by elemental analysis. The complexes of [M2L(OH)2(H2O)] type, where M = Cu(II), Ni(II) or Co(II), were characterized using the data obtained from elemental analyses, molar conductance, IR and electronic spectra, magnetic susceptibility measurements and thermal analysis. These studies support the binuclear formulations of the complexes, of M(II): L (2:1) type.
