Synthesis and Characterization of Some New Transition Metal Complexes of the Schiff Base Derived from Quinoxaline-2-Carboxaldehyde and 2-Aminophenol
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.

A quinoxaline based colorimetric nickel sensor,HQAP[2-(quinoxalin-2-ylmethyleneamine)phenol] with high selectivity and sensitivity toward Ni2+ions is shown to have potential for practical use.
