Abstract

Abstract A novel ligand with double sulfinyl groups, bis (benzylsulfinyl) methane L, was synthesized by a new method. Its novel ternary complex, EuL 2.5⋅ L′·(ClO 4) 2⋅ 5H 2 O, has been synthesized [using L as the first ligand, and benzoic acid L′ as the second ligand], and characterized by elemental analysis, molar conductivity, coordination titration analysis, FTIR, TG–DSC, 1 H NMR and UV–vis. In order to study the effect of the second ...
