Spectroscopic studies on the uranyl-schiff base solid complex (N,N'-p-phenylenebis(salicylideneiminato)UO2)

Abstract The dioxouranium(VI)-Schiff base complex (N,N'- p -phenylenebis(salicylideneiminato)UO 2 ); (UO 2 (sal- p -phdn)) was prepared. Its resonance Raman, infrared and electronic spectra were obtained and assigned on the basis of C 2v symmetry. The force constant and the bond length of the U = O bonds were calculated at 676.2 Nm −1 and 1.74 A, respectively. The electronic absorption band of the complex at 370 nm is assigned to the π-π ∗ transition.
