CrO2 crystallizes in the orthorhombic C222_1 space group. Cr(1) is bonded to one O(2), two equivalent O(3), and three equivalent O(1) atoms to form a mixture of edge and corner-sharing CrO6 octahedra. The corner-sharing octahedral tilt angles range from 3-36°. There are three inequivalent O sites. In the first O site, O(1) is bonded in a trigonal non-coplanar geometry to three equivalent Cr(1) atoms. In the second O site, O(2) is bonded in a bent 150 degrees geometry to two equivalent Cr(1) atoms. In the third O site, O(3) is bonded in a rectangular see-saw-like geometry to four equivalent Cr(1) atoms.

The corner-sharing octahedral tilt angles range from 3-36°. The Cr(1)-O(2) bond length is 1.81 Å. There is one shorter (2.01 Å) and one longer (2.13 Å) Cr(1)-O(3) bond length. There are a spread of Cr(1)-O(1) bond distances ranging from 1.92-1.98 Å. There are three inequivalent O sites.
