SmCuO3 is (Cubic) Perovskite structured and crystallizes in the cubic Pm-3m space group. Sm(1) is bonded to twelve equivalent O(1) atoms to form SmO12 cuboctahedra that share corners with twelve equivalent Sm(1)O12 cuboctahedra, faces with six equivalent Sm(1)O12 cuboctahedra, and faces with eight equivalent Cu(1)O6 octahedra. Cu(1) is bonded to six equivalent O(1) atoms to form CuO6 octahedra that share corners with six equivalent Cu(1)O6 octahedra and faces with eight equivalent Sm(1)O12 cuboctahedra. The corner-sharing octahedra are not tilted. O(1) is bonded to four equivalent Sm(1) and two equivalent Cu(1) atoms to form a mixture of distorted face, corner, and edge-sharing OSm4Cu2 octahedra. The corner-sharing octahedral tilt angles range from 0-60°.
