The compound described by Sm2O is trigonal omega-like structured and crystallizes in the tetragonal I4_1/amd space group. Sm(1) is bonded in a T-shaped geometry to three equivalent O(1) atoms. O(1) is bonded to six equivalent Sm(1) atoms to form a mixture of edge and corner-sharing OSm6 octahedra. The corner-sharing octahedral tilt angles are 8°. is represented by the Crystallographic Information File (CIF) [CIF]
