The crystal structure described by CrO crystallizes in the tetragonal P4_2/m space group. There are three inequivalent Cr sites. In the first Cr site, Cr(1) is bonded in a rectangular see-saw-like geometry to four equivalent O(1) atoms. In the second Cr site, Cr(2) is bonded in a square co-planar geometry to four equivalent O(1) atoms. In the third Cr site, Cr(3) is bonded in a rectangular see-saw-like geometry to four equivalent O(1) atoms. O(1) is bonded to one Cr(1), one Cr(2), and two equivalent Cr(3) atoms to form a mixture of corner and edge-sharing OCr4 trigonal pyramids. is represented by the CIF card [CIF]
