The material described by TbCrO3 is Orthorhombic Perovskite structured and crystallizes in the orthorhombic Pnma space group. Tb(1) is bonded in a 8-coordinate geometry to two equivalent O(1) and six equivalent O(2) atoms. Cr(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form corner-sharing CrO6 octahedra. The corner-sharing octahedral tilt angles are 34°. There are two inequivalent O sites. In the first O site, O(1) is bonded to two equivalent Tb(1) and two equivalent Cr(1) atoms to form distorted corner-sharing OTb2Cr2 trigonal pyramids. In the second O site, O(2) is bonded in a 5-coordinate geometry to three equivalent Tb(1) and two equivalent Cr(1) atoms. is represented by the CIF file [CIF]
