obtain basic knowledge on the complexes of La(III) with some symmetric 1,5-diaryl-3-cyanoformazans. The ionization constants of the formazans as well as the formation constants of their lanthanum complexes were studied potentiometrically m solution by Sarin's method. The La(III) complexes formed were separated and their structures were elucidated by elemental analysis, IR, NMR spectroscopy, thermogravimetry
