Materials Data on TbAsO2 by Materials Project
TbAsO2 crystallizes in the orthorhombic Fddd space group. The structure is three-dimensional. Tb is bonded in a distorted hexagonal planar geometry to six equivalent O atoms. There are a spread of Tb–O bond distances ranging from 2.25–2.40 Å. As is bonded in a linear geometry to two equivalent O atoms. Both As–O bond lengths are 2.08 Å. O is bonded to three equivalent Tb and one As atom to form a mixture of corner and edge-sharing OTb3As tetrahedra.
