Infrared and Raman studies of [UO2(salen)(L)] (L=H2O and CH3OH)

Abstract

The infrared and Raman spectra of [UO2(salen)(H2O)] and [UO2(salen)(CH3OH)] (salen=N,N′-ethylenebis(salicylideneimine) have been recorded. Assignments for the fundamental vibrations are proposed on the basis of C2v symmetry for the former species and Cs for the latter. The calculated values of the stretching force constant of the uranyl group, FUO, are 6.87 and 6.63 mdyn Å−1 for [UO2(salen)(H2O)] and [UO2(salen)(CH3OH)], respectively. The corresponding values of the UO bond lengths calculated as 1.738 and 1.745 Å.
