Title: Materials Data on KHoO2 by Materials Project

Abstract

KHoO2 is Caswellsilverite structured and crystallizes in the trigonal R-3m space group. The structure is three-dimensional. K1+ is bonded to six equivalent O2- atoms to form distorted KO6 octahedra that share corners with six equivalent HoO6 octahedra, edges with six equivalent KO6 octahedra, and edges with six equivalent HoO6 octahedra. The corner-sharing octahedral tilt angles are 15°. All K–O bond lengths are 2.81 Å. Ho3+ is bonded to six equivalent O2- atoms to form HoO6 octahedra that share corners with six equivalent KO6 octahedra, edges with six equivalent KO6 octahedra, and edges with six equivalent HoO6 octahedra. The corner-sharing octahedral tilt angles are 15°. All Ho–O bond lengths are 2.31 Å. O2- is bonded to three equivalent K1+ and three equivalent Ho3+ atoms to form a mixture of distorted edge and corner-sharing OK3Ho3 octahedra. The corner-sharing octahedral tilt angles are 0°.
