The compound described by CeAsO3 is Potassium chlorate-like structured and crystallizes in the monoclinic P2_1/c space group. There are two inequivalent Ce sites. In the first Ce site, Ce(1) is bonded in a 9-coordinate geometry to one O(2), one O(3), two equivalent O(4), two equivalent O(5), and three equivalent O(1) atoms. In the second Ce site, Ce(2) is bonded in a 8-coordinate geometry to one O(5), two equivalent O(2), two equivalent O(3), and three equivalent O(6) atoms. There are two inequivalent As sites. In the first As site, As(1) is bonded in a 3-coordinate geometry to one O(1), one O(2), and one O(3) atom. In the second As site, As(2) is bonded in a distorted trigonal non-coplanar geometry to one O(4), one O(5), and one O(6) atom. There are six inequivalent O sites. In the first O site, O(5) is bonded in a 4-coordinate geometry to one Ce(2), two equivalent Ce(1), and one As(2) atom. In the second O site, O(6) is bonded to three equivalent Ce(2) and one As(2) atom to form a mixture of distorted corner and edge-sharing OCe3As tetrahedra. In the third O site, O(1) is bonded in a 4-coordinate geometry to three equivalent Ce(1) and one As(1) atom. In the fourth O site, O(2) is bonded to one Ce(1), two equivalent Ce(2), and one As(1) atom to form a mixture of distorted corner and edge-sharing OCe3As tetrahedra. In the fifth O site, O(3) is bonded in a 4-coordinate geometry to one Ce(1), two equivalent Ce(2), and one As(1) atom. In the sixth O site, O(4) is bonded in a distorted trigonal non-coplanar geometry to two equivalent Ce(1) and one As(2) atom. is represented by the CIF card [CIF]
