New dioxidouranium (VI) and mixed-valence oxidovanadium (IV/V) coordination compounds with N,O-pentadentate ligands obtained from pyridoxal and triethylenetetramine
چکیده انگلیسی


• Synthesis and structure of [(UO2)(C22H30N6O4)]·MeOH and [(VO)2(O)(C30H36N7O6)]·3MeOH.
• The ligands were obtained from the condensation of pyridoxal and triethylenetetramine.
• The likely mechanisms of formation of imidazoline rings are discussed.
• Electrochemical and UV–Vis studies of the dinuclear vanadium complex were carried out.
• The variation of the oxidation states of VO2+/VO3+ was shown by cyclic voltammetry.

This work describes the synthesis and structural analysis of the uranium and vanadium complexes [(UO2)(C22H30N6O4)]·MeOH (1) and [(VO)2(O)(C30H36N7O6)]·3MeOH (2) with ligands obtained from the condensation of pyridoxal and triethylenetetramine. The probable mechanism for the formation of imidazoline rings in these complexes is described in some details. Finally, electrochemical and UV–Vis studies of the dinuclear vanadium complex were also carried out in order to determine the variation in the oxidation states of the metallic centers (VO2+/VO3+) in DMSO solution.

This work describes the synthesis and structural analysis by X-ray diffraction of uranium and vanadium complexes with ligands obtained from the condensation of pyridoxal and triethylenetetramine. Electrochemical and UV–Vis studies of the dinuclear vanadium complex were also carried out in order to determine the variation in the oxidation states of the metallic centers (VO2+/VO3+).Figure optionsDownload as PowerPoint slide
