CaBi2O4 is Spinel structured and crystallizes in the cubic Fd-3m space group. Ca(1) is bonded to four equivalent O(1) atoms to form CaO4 tetrahedra that share corners with twelve equivalent Bi(1)O6 octahedra. The corner-sharing octahedral tilt angles are 57°. Bi(1) is bonded to six equivalent O(1) atoms to form BiO6 octahedra that share corners with six equivalent Ca(1)O4 tetrahedra and edges with six equivalent Bi(1)O6 octahedra. O(1) is bonded to one Ca(1) and three equivalent Bi(1) atoms to form a mixture of distorted edge and corner-sharing OCaBi3 trigonal pyramids.
