The crystal structure described by CrO2 is Rutile structured and crystallizes in the tetragonal P-42_1m space group. Cr(1) is bonded to six equivalent O(1) atoms to form a mixture of corner and edge-sharing CrO6 octahedra. The corner-sharing octahedral tilt angles range from 49-51°. O(1) is bonded in a distorted trigonal planar geometry to three equivalent Cr(1) atoms. is represented by the CIF card [CIF]
