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.
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°. Both Ca(1)-O(1) bond lengths are 2.48 Å. There are two shorter (2.32 Å) and two longer (2.33 Å) Ca(1)-O(2) bond lengths. Bi(1) is bonded in a rectangular see-saw-like geometry to two equivalent O(1) and two equivalent O(2) atoms. There is one shorter (2.16 Å) and one longer (2.40 Å) Bi(1)-O(1) bond length. Both Bi(1)-O(2) bond lengths are 2.10 Å. 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.
