KBiO3 is (Cubic) Perovskite structured and crystallizes in the cubic Pm-3m space group. K(1) is bonded to twelve equivalent O(1) atoms to form KO12 cuboctahedra that share corners with twelve equivalent K(1)O12 cuboctahedra, faces with six equivalent K(1)O12 cuboctahedra, and faces with eight equivalent Bi(1)O6 octahedra. Bi(1) is bonded to six equivalent O(1) atoms to form BiO6 octahedra that share corners with six equivalent Bi(1)O6 octahedra and faces with eight equivalent K(1)O12 cuboctahedra. The corner-sharing octahedra are not tilted. O(1) is bonded to four equivalent K(1) and two equivalent Bi(1) atoms to form a mixture of distorted edge, corner, and face-sharing OK4Bi2 octahedra. The corner-sharing octahedral tilt angles range from 0-60°.
