The structure described by Ce2AlO3N is (La,Ba)CuO4-derived structured and crystallizes in the tetragonal I4mm space group. There are two inequivalent Ce sites. In the first Ce site, Ce(1) is bonded in a 9-coordinate geometry to four equivalent N(1), one O(2), and four equivalent O(1) atoms. In the second Ce site, Ce(2) is bonded in a 9-coordinate geometry to one N(1), four equivalent O(1), and four equivalent O(2) atoms. Al(1) is bonded to one N(1), one O(2), and four equivalent O(1) atoms to form corner-sharing AlNO5 octahedra. The corner-sharing octahedral tilt angles are 7°. N(1) is bonded to one Ce(2), four equivalent Ce(1), and one Al(1) atom to form distorted NCe5Al octahedra that share  a cornercorner with one O(2)Ce5Al octahedra, corners with four equivalent N(1)Ce5Al octahedra, corners with twelve equivalent O(1)Ce4Al2 octahedra, edges with four equivalent N(1)Ce5Al octahedra, edges with four equivalent O(2)Ce5Al octahedra, and faces with four equivalent O(1)Ce4Al2 octahedra. The corner-sharing octahedral tilt angles range from 0-55°. There are two inequivalent O sites. In the first O site, O(1) is bonded to two equivalent Ce(1), two equivalent Ce(2), and two equivalent Al(1) atoms to form distorted OCe4Al2 octahedra that share corners with two equivalent O(1)Ce4Al2 octahedra, corners with six equivalent N(1)Ce5Al octahedra, corners with six equivalent O(2)Ce5Al octahedra, edges with two equivalent O(1)Ce4Al2 octahedra, faces with two equivalent N(1)Ce5Al octahedra, faces with two equivalent O(2)Ce5Al octahedra, and faces with four equivalent O(1)Ce4Al2 octahedra. The corner-sharing octahedral tilt angles range from 7-55°. In the second O site, O(2) is bonded to one Ce(1), four equivalent Ce(2), and one Al(1) atom to form OCe5Al octahedra that share  a cornercorner with one N(1)Ce5Al octahedra, corners with four equivalent O(2)Ce5Al octahedra, corners with twelve equivalent O(1)Ce4Al2 octahedra, edges with four equivalent N(1)Ce5Al octahedra, edges with four equivalent O(2)Ce5Al octahedra, and faces with four equivalent O(1)Ce4Al2 octahedra.
