UO2 is Hydrophilite structured and crystallizes in the tetragonal P4_2/mnm space group. U(1) is bonded to six equivalent O(1) atoms to form a mixture of corner and edge-sharing UO6 octahedra. The corner-sharing octahedral tilt angles are 52°. O(1) is bonded in a trigonal planar geometry to three equivalent U(1) atoms.

The corner-sharing octahedral tilt angles are 52°. There are two shorter (2.25 Å) and four longer (2.27 Å) U(1)-O(1) bond lengths. O(1) is bonded in a trigonal planar geometry to three equivalent U(1) atoms.
