EuLa2O4 is Spinel structured and crystallizes in the tetragonal I4_1/amd space group. The structure is three-dimensional. Eu2+ is bonded to four equivalent O2- atoms to form EuO4 tetrahedra that share corners with twelve equivalent LaO6 octahedra. The corner-sharing octahedra tilt angles range from 57–60°. All Eu–O bond lengths are 2.46 Å. La3+ is bonded to six equivalent O2- atoms to form LaO6 octahedra that share corners with six equivalent EuO4 tetrahedra and edges with six equivalent LaO6 octahedra. There are two shorter (2.44 Å) and four longer (2.46 Å) La–O bond lengths. O2- is bonded to one Eu2+ and three equivalent La3+ atoms to form a mixture of distorted edge and corner-sharing OLa3Eu trigonal pyramids.
