Abstract
A series of six mixed ligand complexes of the actinide metal
ions, viz., Th(IV) and UO2(VI) with a Schiff base of p-anisidine
and dimethyl sulphoxide and various anions such as acetate, nitrate,
sulpbate and thiocyanate have been synthesized and characterized.
The analytical data include elemental analysis, molecular weight
determinations, conductivity, spectral and thermal studies. The
composition of these complexes are [Th(DMDA)4(DMSO)2(a)4],
[Th(DMDA)4(DMSO)2(aa)2], [UO2(DMDA)2(DMSO)2(a)2] and
[UO2(DMDA)2(DMSO)2(aa)], Where DMDA = 4,4' -dimethyl diphenyl
azomethine, a = monovalent anion such as acetate, nitrate
and thiocyanate and aa = divalent' anion such as sulphate. In these
complexes schiff base of p-anisidine acts as a neutral monodentate
ligand, DMSO and monovalent anion acts as unidentate ligand and
divalent sulphate ion acts as a bidentate ligand.
