The compound described by TbCr2O2 crystallizes in the tetragonal I4_1/amd space group. Tb(1) is bonded in a linear geometry to two equivalent O(1) atoms. Cr(1) is bonded in a 3-coordinate geometry to three equivalent O(1) atoms. O(1) is bonded in a distorted rectangular see-saw-like geometry to one Tb(1) and three equivalent Cr(1) atoms. is represented by the CIF card [CIF]
