The material described by TmLaO2 is Caswellsilverite structured and crystallizes in the trigonal R-3m space group. Tm(1) is bonded to six equivalent O(1) atoms to form TmO6 octahedra that share corners with six equivalent La(1)O6 octahedra, edges with six equivalent Tm(1)O6 octahedra, and edges with six equivalent La(1)O6 octahedra. The corner-sharing octahedral tilt angles are 13°. La(1) is bonded to six equivalent O(1) atoms to form distorted LaO6 octahedra that share corners with six equivalent Tm(1)O6 octahedra, edges with six equivalent Tm(1)O6 octahedra, and edges with six equivalent La(1)O6 octahedra. The corner-sharing octahedral tilt angles are 13°. O(1) is bonded to three equivalent Tm(1) and three equivalent La(1) atoms to form a mixture of corner and edge-sharing OLa3Tm3 octahedra. The corner-sharing octahedra are not tilted. is represented by the CIF file [CIF]
