The compound described by TmBiO3 is Ilmenite-like structured and crystallizes in the trigonal R3c space group. Tm(1) is bonded to six equivalent O(1) atoms to form distorted TmO6 octahedra that share corners with three equivalent Bi(1)O6 octahedra, corners with six equivalent Tm(1)O6 octahedra, edges with three equivalent Bi(1)O6 octahedra, and  a faceface with one Bi(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 39-69°. Bi(1) is bonded to six equivalent O(1) atoms to form distorted BiO6 octahedra that share corners with three equivalent Tm(1)O6 octahedra, corners with six equivalent Bi(1)O6 octahedra, edges with three equivalent Tm(1)O6 octahedra, and  a faceface with one Tm(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 57-69°. O(1) is bonded in a distorted see-saw-like geometry to two equivalent Tm(1) and two equivalent Bi(1) atoms. is represented by the CIF file [CIF]
