Tb(AsO)2 crystallizes in the tetragonal I4_1/amd space group. The structure is zero-dimensional and consists of eight Tb(AsO)2 clusters. Tb(1) is bonded in a distorted linear geometry to two equivalent O(1) atoms. As(1) is bonded in a single-bond geometry to one O(1) atom. O(1) is bonded in a water-like geometry to one Tb(1) and one As(1) atom.
Tb(AsO)2 crystallizes in the tetragonal I4_1/amd space group. The structure is zero-dimensional and consists of eight Tb(AsO)2 clusters. Tb(1) is bonded in a distorted linear geometry to two equivalent O(1) atoms. Both Tb(1)-O(1) bond lengths are 2.23 Å. As(1) is bonded in a single-bond geometry to one O(1) atom. The As(1)-O(1) bond length is 1.77 Å. O(1) is bonded in a water-like geometry to one Tb(1) and one As(1) atom.
