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.
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. All Cr(1)-O(1) bond lengths are 2.08 Å. In the second Cr site, Cr(2) is bonded in a square co-planar geometry to four equivalent O(1) atoms. All Cr(2)-O(1) bond lengths are 2.08 Å. In the third Cr site, Cr(3) is bonded in a rectangular see-saw-like geometry to four equivalent O(1) atoms. There are two shorter (2.07 Å) and two longer (2.09 Å) Cr(3)-O(1) bond lengths. 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.
