The material structure described by Cs3AsO4 crystallizes in the orthorhombic Pnma space group. There are two inequivalent Cs sites. In the first Cs site, Cs(1) is bonded in a 7-coordinate geometry to two equivalent O(2), two equivalent O(3), and three equivalent O(1) atoms. In the second Cs site, Cs(2) is bonded in a 6-coordinate geometry to one O(2), one 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 distorted single-bond geometry to two equivalent Cs(2), three equivalent Cs(1), and one As(1) atom. In the second O site, O(2) is bonded in a distorted single-bond geometry to one Cs(2), four equivalent Cs(1), and one As(1) atom. In the third O site, O(3) is bonded in a distorted single-bond geometry to one Cs(2), four equivalent Cs(1), and one As(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
