The compound described by SmAsO4 is Zircon-like structured and crystallizes in the tetragonal I4_1/a space group. Sm(1) is bonded in a 8-coordinate geometry to eight equivalent O(1) atoms. As(1) is bonded in a tetrahedral geometry to four equivalent O(1) atoms. O(1) is bonded in a distorted trigonal planar geometry to two equivalent Sm(1) and one As(1) atom. is represented by the CIF card [CIF]
