Dibasic tridentate Schiff bases obtained by the condensation of O ‐aminobenzoic acid with salicyldehyde and its 5‐chloro and 5‐bromo derivatives were synthesised and used to pracipitate Zr(IV), Th(IV) and UO 2 (VI) metals as complexes. The 1:1 (metal‐ligand) stoichiometry of these complexes is shown by elemental analysis, gravimetric estimations and conductometric titrations while the structures of the complexes are proved by i.r. spectra and thermogravimetric analysis. The magnetic susceptibility measurements by Gouy method show, these complexes to be monormeic and diamagnetic. The molar conductance values in nitrobenzene indicate the nonelectrolytic behaviour of the complexes. The results show that the complexes of the type Zr(OH) 2 L.H 2 O, Th(OH) 2 L.H 2 O and UO 2 L.H 2 O are formed having solvent molecule in co‐ordination with metal ion.
