Materials Data on YBiO3 by Materials Project

Abstract

BiYO3 is Ilmenite-like structured and crystallizes in the trigonal R3c space group. The structure is three-dimensional. Y3+ is bonded to six equivalent O2- atoms to form distorted YO6 octahedra that share corners with three equivalent BiO6 octahedra, corners with six equivalent YO6 octahedra, edges with three equivalent BiO6 octahedra, and a faceface with one BiO6 octahedra. The corner-sharing octahedra tilt angles range from 42–69°. There are three shorter (2.25 Å) and three longer (2.36 Å) Y–O bond lengths. Bi3+ is bonded to six equivalent O2- atoms to form distorted BiO6 octahedra that share corners with three equivalent YO6 octahedra, corners with six equivalent BiO6 octahedra, edges with three equivalent YO6 octahedra, and a faceface with one YO6 octahedra. The corner-sharing octahedra tilt angles range from 54–69°. There are three shorter (2.33 Å) and three longer (2.51 Å) Bi–O bond lengths. O2- is bonded in a distorted see-saw-like geometry to two equivalent Y3+ and two equivalent Bi3+ atoms.
