CaBiO3 is Ilmenite structured and crystallizes in the trigonal R-3 space group. Ca(1) is bonded to six equivalent O(1) atoms to form distorted CaO6 pentagonal pyramids that share corners with nine equivalent Bi(1)O6 octahedra, edges with three equivalent Ca(1)O6 pentagonal pyramids, and  a faceface with one Bi(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 46-66°. Bi(1) is bonded to six equivalent O(1) atoms to form distorted BiO6 octahedra that share corners with nine equivalent Ca(1)O6 pentagonal pyramids, edges with three equivalent Bi(1)O6 octahedra, and  a faceface with one Ca(1)O6 pentagonal pyramid. O(1) is bonded to two equivalent Ca(1) and two equivalent Bi(1) atoms to form a mixture of distorted corner and edge-sharing OCa2Bi2 trigonal pyramids.
