Ternary lanthanide complexes of the type M(HSal)3(TBP)2: Preparation and spectroscopic studies

Ternary lanthanide complexes of the general formula M(Hsal)3(TBP)2, where M(III) = lanthanide or yttrium ion, Hsal = salicylate ion = C6H4(OH)COO- and TBP = tri-n-butylphosphate, have been prepared by a liquid-liquid extraction method. The coordinated nature of the salicylate ion and TBP has been es...
