Abstract


Two monobasIc trldentates. namely o-(N-()!-furfuraldimino)phenol (HFP) and o-{N-thiophene-2-aldimino)phenol (HTP) and their bivalent metal chelates were synthesised and studied by physicochemical techniques. Potentiometric studies were carried out in 30%(vjv) dioxane-water media (j.l=O.Ol, 0.05 and 0.1 M NaCI04 ) at 25.35 and 45°C. The solid metal chelates were characterised by molecular mass, elemental analysis, conductance, magnetic, thermal and spectral analyses and were assigned 1 :2(rnetal- ligand) stoichiometry, in which the bivalent metals showed six coordination number. Some spectral parameters were also evaluated.
