RbCuO3 is (Cubic) Perovskite structured and crystallizes in the cubic Pm-3m space group. Rb(1) is bonded to twelve equivalent O(1) atoms to form RbO12 cuboctahedra that share corners with twelve equivalent Rb(1)O12 cuboctahedra, faces with six equivalent Rb(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 Rb(1)O12 cuboctahedra. The corner-sharing octahedra are not tilted. O(1) is bonded to four equivalent Rb(1) and two equivalent Cu(1) atoms to form a mixture of distorted corner, edge, and face-sharing ORb4Cu2 octahedra. The corner-sharing octahedral tilt angles range from 0-60°.
