The material described by GdAsO4 is Zircon-like structured and crystallizes in the monoclinic P2_1/m space group. Gd(1) is bonded in a 8-coordinate geometry to two equivalent O(2), two equivalent O(3), and four equivalent O(1) atoms. As(1) is bonded in a tetrahedral geometry to one O(2), one O(3), and two equivalent O(1) atoms. There are three inequivalent O sites. In the first O site, O(1) is bonded in a 3-coordinate geometry to two equivalent Gd(1) and one As(1) atom. In the second O site, O(2) is bonded in a 3-coordinate geometry to two equivalent Gd(1) and one As(1) atom. In the third O site, O(3) is bonded in a 3-coordinate geometry to two equivalent Gd(1) and one As(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
