CrO2 is Hydrophilite-like structured and crystallizes in the orthorhombic Pnma space group. Cr(1) is bonded to three equivalent O(1) and three equivalent O(2) atoms to form a mixture of corner and edge-sharing CrO6 octahedra. The corner-sharing octahedral tilt angles are 51°. There are two inequivalent O sites. In the first O site, O(2) is bonded in a trigonal non-coplanar geometry to three equivalent Cr(1) atoms. In the second O site, O(1) is bonded in a trigonal planar geometry to three equivalent Cr(1) atoms.
