The crystal structure described by Sm(AsO)2 is Indium-like structured and crystallizes in the tetragonal I4_1/amd space group. The structure is zero-dimensional and consists of eight Sm(AsO)2 clusters. Sm(1) is bonded in a linear geometry to two equivalent O(1) atoms. As(1) is bonded in a distorted single-bond geometry to one O(1) atom. O(1) is bonded in a water-like geometry to one Sm(1) and one As(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
