Synthesis, Spectral and Thermal Studies of VO(IV) and UO2(VI) Complexes with N,N'-Triethylenediamine-bis(3-carboxypropenamide)

Abstract

The complexes of VO(IV) and UO₂(VI) with N,N'-triethylenediamine-bis(3-carboxypropenamide) (TEBCPH₂) have been synthesized and characterized by chemical analysis, conductance, magnetic, infrared spectral and thermal studies. On the basis of the above studies it is concluded that the ligand acts as hexadentate in dioxouranium(VI) complex whereas in the oxovanadium(IV) complex the ligand shows tetradentate nature. The VO(IV) and UO₂(VI) complexes have been assigned the formulae [VO(TEBCP)]·2H₂O and [UO₂(TEBCP)] respectively.
