The structure described by Eu2VO4 is (La,Ba)CuO4 structured and crystallizes in the tetragonal I4/mmm space group. Eu(1) is bonded in a 9-coordinate geometry to four equivalent O(2) and five equivalent O(1) atoms. V(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form corner-sharing VO6 octahedra. The corner-sharing octahedra are not tilted. There are two inequivalent O sites. In the first O site, O(2) is bonded to four equivalent Eu(1) and two equivalent V(1) atoms to form distorted OEu4V2 octahedra that share corners with two equivalent O(2)Eu4V2 octahedra, corners with twelve equivalent O(1)Eu5V octahedra, edges with two equivalent O(2)Eu4V2 octahedra, faces with four equivalent O(2)Eu4V2 octahedra, and faces with four equivalent O(1)Eu5V octahedra. The corner-sharing octahedral tilt angles range from 0-55°. In the second O site, O(1) is bonded to five equivalent Eu(1) and one V(1) atom to form distorted OEu5V octahedra that share corners with five equivalent O(1)Eu5V octahedra, corners with twelve equivalent O(2)Eu4V2 octahedra, edges with eight equivalent O(1)Eu5V octahedra, and faces with four equivalent O(2)Eu4V2 octahedra. The corner-sharing octahedral tilt angles range from 0-55°. is represented by the Crystallographic Information File (CIF) [CIF]
