Electronic Properties, Redox Behavior, and Interactions with H2O2 of pH-Sensitive Hydroxyphenyl-1,2,4-triazole-Based Oxovanadium(V) Complexes

Bis(methanol-κO)dioxido[3,3'-(1H-1,2,4-triazole-3,5-diyl)diphenolato-κ3O,N4,O']uranium(VI) methanol monosolvate

The structure of the title compound, [U(C(14)H(9)N(3)O(2))O(2)(CH(3)OH)(2)]·CH(3)OH, is the first to be reported for an actinide complex including triazole ligands. The U(VI) atom exhibits a pentagonal-bipyramidal NO(6) coordination environment, involving two axial oxide ligands [U=O = 1.766 (3) and 1.789 (3) Å], four equatorial O atoms [U-O = 2.269 (3)-2.448 (3) Å] from the ligand and the two coordinated methanol molecules, and one equatorial N atom [U-N = 2.513 (4) Å] from the ligand. In the crystal structure, the complex molecules are linked via intermolecular N-H...O and O-H...O hydrogen bonds to form a two-dimensional structure.
