The material described by TmCoO3 is Orthorhombic Perovskite structured and crystallizes in the orthorhombic Pnma space group. Tm(1) is bonded in a 8-coordinate geometry to two equivalent O(1) and six equivalent O(2) atoms. Co(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form corner-sharing CoO6 octahedra. The corner-sharing octahedral tilt angles range from 36-38°. There are two inequivalent O sites. In the first O site, O(1) is bonded to two equivalent Tm(1) and two equivalent Co(1) atoms to form distorted corner-sharing OTm2Co2 trigonal pyramids. In the second O site, O(2) is bonded in a 5-coordinate geometry to three equivalent Tm(1) and two equivalent Co(1) atoms. is represented by the CIF card [CIF]
