Synthesis, magnetic and mass spectrometric studies on dinuclear complexes based on Schiff-base triazolic ligands

Abstract

A series of dinuclear complexes of Ni^II, Co^II and Cu^II have been prepared by template 1 : 2 condensation of 3,5-diacetyl-1,2,4-triazole and the corresponding aniline in the presence of 1 equivalent of lithium hydroxide and the corresponding metal(II) salt. The dinuclear nature of the nickel and cobalt compounds have been demonstrated by FAB mass spectrometry and magnetic measurements, which indicate the presence of antiferromagnetic exchange interactions.
