Materials Data on YOF by Materials Project

Abstract

YOF crystallizes in the tetragonal P4/nmm space group. The structure is three-dimensional. Y3+ is bonded in a body-centered cubic geometry to four equivalent O2- and four equivalent F1- atoms. All Y–O bond lengths are 2.26 Å. All Y–F bond lengths are 2.51 Å. O2- is bonded to four equivalent Y3+ atoms to form distorted OY4 tetrahedra that share corners with four equivalent OY4 tetrahedra, corners with twelve equivalent FY4 tetrahedra, edges with two equivalent FY4 tetrahedra, and edges with four equivalent OY4 tetrahedra. F1- is bonded to four equivalent Y3+ atoms to form distorted FY4 tetrahedra that share corners with four equivalent FY4 tetrahedra, corners with twelve equivalent OY4 tetrahedra, edges with two equivalent OY4 tetrahedra, and edges with four equivalent FY4 tetrahedra.
