摘要:
The Schiff base ligand 2-[2'-hydroxysalicylidene-5'-(2"-thiazolylazo)]phenol was prepared and characterized. The ligand yields binuclear complexes of the type [ML(H2O)(2)](2) [H2L=2-[2'-hydroxysalicylidene-5'- (2"-thiazolyl azo] phenol, M=Mn(II), Co(II), Ni(II), Cu(II) and Zn(II)] have been synthesized and characterized by elemental analyses, magnetic susceptibility, molar conductance, IR, electronic spectra and thermal analysis (TGA). The ESR spectra of the Cu(II) complex were studied resulting in g(parallel to) > g(perpendicular to) > 2.0023. The N2O2 environment of the metal ion is realized in the complexes by involvement of the -N=N- group in coordination. The magnetic moments and electronic spectra indicate octahedral geometry for the Mn(II), Co(II), Ni(II) and Zn(II) complexes and distorted octahedral geometry for the Cu(II) complex.
