Materials Data on GdOF by Materials Project

Abstract

GdOF crystallizes in the tetragonal P4/nmm space group. The structure is three-dimensional. Gd3+ is bonded in a body-centered cubic geometry to four equivalent O2- and four equivalent F1- atoms. All Gd–O bond lengths are 2.29 Å. All Gd–F bond lengths are 2.54 Å. O2- is bonded to four equivalent Gd3+ atoms to form distorted OGd4 tetrahedra that share corners with four equivalent OGd4 tetrahedra, corners with twelve equivalent FGd4 tetrahedra, edges with two equivalent FGd4 tetrahedra, and edges with four equivalent OGd4 tetrahedra. F1- is bonded to four equivalent Gd3+ atoms to form distorted FGd4 tetrahedra that share corners with four equivalent FGd4 tetrahedra, corners with twelve equivalent OGd4 tetrahedra, edges with two equivalent OGd4 tetrahedra, and edges with four equivalent FGd4 tetrahedra.
