The structure described by SrCeVO4 is (La,Ba)CuO4-derived structured and crystallizes in the tetragonal I4mm space group. Sr(1) is bonded in a 9-coordinate geometry to one O(2), four equivalent O(1), and four equivalent O(3) atoms. Ce(1) is bonded in a 9-coordinate geometry to one O(3), four equivalent O(1), and four equivalent O(2) atoms. V(1) is bonded to one O(2), one O(3), and four equivalent O(1) atoms to form corner-sharing VO6 octahedra. The corner-sharing octahedral tilt angles are 6°. There are three inequivalent O sites. In the first O site, O(1) is bonded to two equivalent Sr(1), two equivalent Ce(1), and two equivalent V(1) atoms to form distorted OSr2Ce2V2 octahedra that share corners with two equivalent O(1)Sr2Ce2V2 octahedra, corners with six equivalent O(3)Sr4CeV octahedra, corners with six equivalent O(2)SrCe4V octahedra, edges with two equivalent O(1)Sr2Ce2V2 octahedra, faces with two equivalent O(3)Sr4CeV octahedra, faces with two equivalent O(2)SrCe4V octahedra, and faces with four equivalent O(1)Sr2Ce2V2 octahedra. The corner-sharing octahedral tilt angles range from 6-53°. In the second O site, O(2) is bonded to one Sr(1), four equivalent Ce(1), and one V(1) atom to form distorted OSrCe4V octahedra that share  a cornercorner with one O(3)Sr4CeV octahedra, corners with four equivalent O(2)SrCe4V octahedra, corners with twelve equivalent O(1)Sr2Ce2V2 octahedra, edges with four equivalent O(3)Sr4CeV octahedra, edges with four equivalent O(2)SrCe4V octahedra, and faces with four equivalent O(1)Sr2Ce2V2 octahedra. The corner-sharing octahedral tilt angles range from 0-53°. In the third O site, O(3) is bonded to four equivalent Sr(1), one Ce(1), and one V(1) atom to form distorted OSr4CeV octahedra that share  a cornercorner with one O(2)SrCe4V octahedra, corners with four equivalent O(3)Sr4CeV octahedra, corners with twelve equivalent O(1)Sr2Ce2V2 octahedra, edges with four equivalent O(3)Sr4CeV octahedra, edges with four equivalent O(2)SrCe4V octahedra, and faces with four equivalent O(1)Sr2Ce2V2 octahedra.
