The structure described by CaBiO3 crystallizes in the orthorhombic Pnma space group. Ca(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form corner-sharing CaO6 octahedra. The corner-sharing octahedral tilt angles range from 51-56°. Bi(1) is bonded in a rectangular see-saw-like geometry to two equivalent O(1) and two equivalent O(2) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded to two equivalent Ca(1) and two equivalent Bi(1) atoms to form distorted corner-sharing OCa2Bi2 trigonal pyramids. In the second O site, O(2) is bonded in a trigonal planar geometry to two equivalent Ca(1) and one Bi(1) atom. is represented by the CIF file [CIF]
