ABSTRACT:

The complexes of Cr(III), Mn(II), Fe(III), Co(II), Ni(II), Cu(II), Zn(II), Cd(II) and Hg(II) with 2-methyl-benzoxazole-5-carboxylic acid (2-hydroxy-benzylidene)-hydrazide [MBCHBH] have been synthesized and structurally characterized on the basis of analytical, conductance, thermal, magnetic and infrared, electronic and esr spectral data. The ligand MBCHBH behaves as a mononegative, tridentate one coordinating through phenolic oxygen, amid group oxygen and azomethine nitrogen.
