Crystal structure of aqua­(nitrato-κO)dioxido{2-3-(pyridin-2-yl-κN)-1H-124-triazol-5-yl-κN4phenolato-κO}uranium(VI) aceto­nitrile monosolvate monohydrate

摘要

In the title compound, [U(C13H9N4O)(NO3)O2(H2O)]·CH3CN·H2O, the U^VI atom is seven-coordinated in a distorted penta­gonal–bipyramidal N2O5 manner by one tridentate triazole ligand, one monodentate nitrate anion and one water mol­ecule in the equatorial plane and by two uran­yl(VI) O atoms in the axial positions. In the crystal, the U^VI complex mol­ecule is linked to the water and aceto­nitrile solvent mol­ecules through N—H⋯N, O—H⋯O and O—H⋯N hydrogen bonds, forming a sheet structure parallel to the bc plane. The sheets are further linked by an additional O—H⋯O hydrogen bond, forming a three-dimensional network.
