Crystal structure of aqua(nitrato-jO)dioxido{2-[3-(pyridin-2-yl-kN)-1 H-1,2,4-triazol-5-yl-kN4]-phenolato-jO}uranium(VI) acetonitrile monosolvate monohydrate

Abstract

In the title compound, [U(C13H9N4O)(NO3)O2(H2O)]·CH3CN·H2O, the UVI 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 UVI 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.
