The compound described by TbAsO2 crystallizes in the tetragonal I4_1/amd space group. Tb(1) is bonded in a distorted hexagonal planar geometry to six equivalent O(1) atoms. As(1) is bonded in a linear geometry to two equivalent O(1) atoms. O(1) is bonded to three equivalent Tb(1) and one As(1) atom to form a mixture of corner and edge-sharing OTb3As tetrahedra. is represented by the CIF file [CIF]
