The “periodic table” of benzotriazoles: Uranium(VI) complexes

•Benzotriazoles have been employed as ligands in uranium(VI) chemistry.•Hexagonal bipyramidal uranyl complexes have been structurally characterized.•The complexes have been studied by Raman, IR and 1H-NMR spectroscopies.

The first employment of benzotriazoles in uranium(VI) chemistry has led to uranyl complexes with interesting structures and spectroscopic properties; the reactions of uranyl nitrate with 5,6-dimethylbenzotriazole give two products depending on the reactants' molar ratio.
