Abstract

The azodye ligands were synthesized from the coupling of 3-methyl-1-phenyl-1H-pyrazol-5(4H)-one with aniline derivatives and characterized by elemental analyses, IR and NMR spectroscopy. Dioxouranium (VI) complexes of the prepared ligands were characterized by elemental analyses, conductance, thermal analysis and spectral (UV, IR and NMR) results. IR spectra show that the ligands behave as a monobasic bidentate coordinating via the hydrazo nitrogen atom and CO of the pyrazole ring. Thermal studies to verify the status of water molecules inside or outside the coordination sphere of the central metal ion. The optimized bond lengths, bond angles and the calculated quantum chemical parameters for the ligands were investigated. The coordination geometries and electronic structures are determined from a framework for the modeling of the complexes. The force constants, FUO (10-8 N/Ao) and the bond lengths, RUO (Ao) have been calculated from an asymmetric stretching frequency of O-U-Ogroup.
