Materials Data on CsAsO3 by Materials Project

CsAsO3 crystallizes in the trigonal P-31m space group. The structure is two-dimensional and consists of one CsAsO3 sheet oriented in the (0, 0, 1) direction. Cs1+ is bonded in a 3-coordinate geometry to three equivalent O2- atoms. All Cs–O bond lengths are 2.73 Å. As5+ is bonded to six equivalent O2- atoms to form edge-sharing AsO6 octahedra. All As–O bond lengths are 1.88 Å. O2- is bonded in a 3-coordinate geometry to one Cs1+ and two equivalent As5+ atoms.

Materials Data on CsAsO3 by Materials Project

CsAsO3 is (Cubic) Perovskite structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Cs1+ is bonded to twelve equivalent O2- atoms to form CsO12 cuboctahedra that share corners with twelve equivalent CsO12 cuboctahedra, faces with six equivalent CsO12 cuboctahedra, and faces with eight equivalent AsO6 octahedra. All Cs–O bond lengths are 2.88 Å. As5+ is bonded to six equivalent O2- atoms to form AsO6 octahedra that share corners with six equivalent AsO6 octahedra and faces with eight equivalent CsO12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. All As–O bond lengths are 2.04 Å. O2- is bonded to four equivalent Cs1+ and two equivalent As5+ atoms to form a mixture of distorted corner, edge, and face-sharing OCs4As2 octahedra. The corner-sharing octahedra tilt angles range from 0–60°.
