OsO2 is Hydrophilite structured and crystallizes in the tetragonal P4_2/mnm space group. Os(1) is bonded to six equivalent O(1) atoms to form a mixture of edge and corner-sharing OsO6 octahedra. The corner-sharing octahedral tilt angles are 53°. O(1) is bonded in a trigonal planar geometry to three equivalent Os(1) atoms.

The corner-sharing octahedral tilt angles are 53°. There are two shorter (1.95 Å) and four longer (2.01 Å) Os(1)-O(1) bond lengths. O(1) is bonded in a trigonal planar geometry to three equivalent Os(1) atoms.
