摘要:
                                Some new transition metal complexes of the Schiff base quinoxaline-2-carboxalidene-2-aminophenol (HQAP) have been synthesized and characterized by elemental analyses, conductance and magnetic measurements and IR and UV-Visible spectral studies. The complexes have the following empirical formulae: [Mn(QAP)(2)], [Fe(QAP)(2)Cl], [Co(QAP)(2)], [Ni(QAP)(2)] and [Cu(QAP)(2)]. A tetrahedral structure has been assigned for the manganese(II), cobalt(II), nickel(II) and copper(II) complexes. For the iron(III) complex an octahedral dimeric structure has been suggested.
