The compound described by DyCr2O2 crystallizes in the tetragonal I4_1/amd space group. Dy(1) is bonded in a linear geometry to two equivalent O(1) atoms. Cr(1) is bonded in a 4-coordinate geometry to four equivalent O(1) atoms. O(1) is bonded to one Dy(1) and four equivalent Cr(1) atoms to form a mixture of distorted edge and corner-sharing ODyCr4 trigonal bipyramids. is represented by the CIF file [CIF]
