Synthesis, characterization and spectral studies of Y (III)‎, La (II)‎ and Rh (III)‎ complexes with 2,4-dimethyl-6-(4-nitro-phenylazo)‎-phenol

Abstract EN

Transition metal complexes of Y(III), La(III) and Rh(III) with azo dye 2,4-dimethyl-6- (4-nitro-phenylazo)-phenol derived from 4-nitroaniline and 2,4-dimethylphenol were synthesized.

Characterization of these compounds has been done on the basis of elemental analysis, electronic data, FT-IR,UV-Vis and 1HNMR, as well as conductivity measurements.

The nature of the complexes formed were studies following the mole ratio and continuous variation methods, Beer's law obeyed over a concentration range (1x10-4- 3x10-4).

High molar absorbtivity of the complex solutions were observed.

From the analytical data, the stoichiomerty of the complexes has been found to be 1:3 (Metal:ligand).

On the basis of Physicochemical data octahedral geometries were assigned for the complexes.
