The formation equilibria of the complexes of some transition metal ion
s with sulphadimidine (SDD) have been investigated by a potentiometric
technique. The stepwise formation constants of the complexes formed i
n solution were calculated using the non-lineal least-squares computer
program MINIQUAD. The concentration distribution of the complex speci
es was determined. Complexes of Cu(II), Cr(III), Mi(II), Co(II), zn(II
), Hg(II), Cd(II), UO2(VI) and Pd(II) have been synthesized and charac
terized by elemental analyses, electrolytic conductance, electronic, I
R, H-1 NMR, and mass spectra and thermogravimetric studies. The-ligand
forms 1:1 complexes (metal ion : ligand) with Cu(II), Zn(II), Hg(II),
Cd(II), UO2(VI) and Pd(II) and 1:2 complexes with Cr(III), NI(II) and
Co(II).
