The Schiff base synthesised by condensing o-aminobenzoic acid and terephtbalaldehyde in ethanolic medium, forms complexes [ML.2H₂O]_n with Mn(II), Co(II), Ni(ll), Cu(II), Zn(II) and Cd(II). These were obtained by refluxing the metal : ligand :: 1 : 1 in dimethylformamide. The polymeric octahedral structures of the insoluble complexes have been arrived at on the basis of elemental, ir and rs studies, magnetic measurements and thermal analysis.
