Synthesis and Spectroscopic Studies of NN-O-Phenylenebis (Salicylideneiminato) Dioxouranium (VI) Solvates (L) CL = DMF and PY)

Abstract

Abstract The two new complexes [UO2 (sal-o-phdn) (DMF)] and [UO2 (sol-o-phdn) (py)] (sal-o-phdn = N′-o-phenylenebis (salicylideneiminato) have been synthesized and their infrared and electronic spectra have been obtained and assigned beside those of the related complex [UO2 (sal -o-phdn)(EtOH)]. The values of both the bond stretching force constant of the uranyl bond, FU=O′ and U = O bond length have been calculated for each complex. The structure and geometry for each of the newlv prepared DMF and py complexes are discussed and compared with those known for the EtOH complex.
