The structure described by DyCe4O9 crystallizes in the orthorhombic Imm2 space group. Dy(1) is bonded in a 6-coordinate geometry to two equivalent O(2), two equivalent O(4), and two equivalent O(5) atoms. There are two inequivalent Ce sites. In the first Ce site, Ce(1) is bonded in a body-centered cubic geometry to one O(2), one O(4), three equivalent O(1), and three equivalent O(3) atoms. In the second Ce site, Ce(2) is bonded in a 7-coordinate geometry to one O(1), one O(3), one O(5), two equivalent O(2), and two equivalent O(4) atoms. There are five inequivalent O sites.

In the third O site, O(3) is bonded to one Ce(2) and three equivalent Ce(1) atoms to form OCe4 tetrahedra that share  a cornercorner with one O(5)Ce2Dy2 tetrahedra,  a cornercorner with one O(4)Ce3Dy tetrahedra, corners with two equivalent O(1)Ce4 tetrahedra, corners with five equivalent O(2)Ce3Dy tetrahedra, corners with six equivalent O(3)Ce4 tetrahedra, edges with two equivalent O(4)Ce3Dy tetrahedra, and edges with four equivalent O(1)Ce4 tetrahedra. In the fourth O site, O(4) is bonded to one Dy(1), one Ce(1), and two equivalent Ce(2) atoms to form OCe3Dy tetrahedra that share  a cornercorner with one O(3)Ce4 tetrahedra, corners with three equivalent O(2)Ce3Dy tetrahedra, corners with three equivalent O(4)Ce3Dy tetrahedra, corners with five equivalent O(1)Ce4 tetrahedra, edges with two equivalent O(5)Ce2Dy2 tetrahedra, edges with two equivalent O(2)Ce3Dy tetrahedra, and edges with two equivalent O(3)Ce4 tetrahedra. In the fifth O site, O(5) is bonded to two equivalent Dy(1) and two equivalent Ce(2) atoms to form OCe2Dy2 tetrahedra that share corners with two equivalent O(5)Ce2Dy2 tetrahedra, corners with two equivalent O(1)Ce4 tetrahedra, corners with two equivalent O(3)Ce4 tetrahedra, corners with eight equivalent O(2)Ce3Dy tetrahedra, and edges with four equivalent O(4)Ce3Dy tetrahedra. is represented by the CIF card [CIF]
