The material described by CeAsO3 is Potassium chlorate structured and crystallizes in the monoclinic P2_1/m space group. Ce(1) is bonded in a 9-coordinate geometry to three equivalent O(1) and six equivalent O(2) atoms. As(1) is bonded in a 3-coordinate geometry to one O(1) and two equivalent O(2) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded in a 1-coordinate geometry to three equivalent Ce(1) and one As(1) atom. In the second O site, O(2) is bonded to three equivalent Ce(1) and one As(1) atom to form a mixture of distorted edge and corner-sharing OCe3As tetrahedra. is represented by the CIF file [CIF]
