Bis-(3,5-dimethyl salicylidine)-ethylenediamine as a Gravimetric Reagent for Cu(II)

Abstract

Complex of Cu(II) with bis-(3,5-dimethyl salicylidine)-ethylenediamine was synthesized and characterized by elemental analysis, melting point determination, conductivity measurement, magnetic and spectroscopic studies. Molecular formula of the newly prepared complex was determined as C20H22N2O2Cu and the probable geometry has been suggested as square planar. Gravimetric estimation of Cu(II) was made with bis-(3,5-dimethyl salicylidine)-ethylenediamine and the result was compared with the known method of estimation of Cu(II) iodometrically. It was found that the result of estimation with newly prepared reagent was as good as the reported result of estimation of Cu(II) iodometrically.
