Abstract :
In the title compound, [U(C13H9N4O)(NO3)O2(H2O)]CH3CNH2O, 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—HN, O—HO and O—HN
hydrogen bonds, forming a sheet structure parallel to the bc plane. The sheets
are further linked by an additional O—HO hydrogen bond, forming a threedimensional network.
