Title: Materials Data on KAsO3 by Materials Project

Abstract

KAsO3 is (Cubic) Perovskite structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. K1+ is bonded to twelve equivalent O2- atoms to form KO12 cuboctahedra that share corners with twelve equivalent KO12 cuboctahedra, faces with six equivalent KO12 cuboctahedra, and faces with eight equivalent AsO6 octahedra. All K–O bond lengths are 2.72 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 KO12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. All As–O bond lengths are 1.92 Å. O2- is bonded to four equivalent K1+ and two equivalent As5+ atoms to form a mixture of distorted edge, face, and corner-sharing OK4As2 octahedra. The corner-sharing octahedra tilt angles range from 0–60°.
