The structure described by SrEuTi4O12 crystallizes in the tetragonal P4/mmm space group. Sr(1) is bonded to four equivalent O(2) and eight equivalent O(1) atoms to form SrO12 cuboctahedra that share corners with four equivalent Sr(1)O12 cuboctahedra, corners with eight equivalent Eu(1)O12 cuboctahedra, and faces with eight equivalent Ti(1)O6 octahedra. Eu(1) is bonded to four equivalent O(3) and eight equivalent O(1) atoms to form EuO12 cuboctahedra that share corners with four equivalent Eu(1)O12 cuboctahedra, corners with eight equivalent Sr(1)O12 cuboctahedra, and faces with eight equivalent Ti(1)O6 octahedra. Ti(1) is bonded to one O(2), one O(3), and four equivalent O(1) atoms to form TiO6 octahedra that share corners with six equivalent Ti(1)O6 octahedra, faces with two equivalent Sr(1)O12 cuboctahedra, and faces with two equivalent Eu(1)O12 cuboctahedra. The corner-sharing octahedra are not tilted. There are three inequivalent O sites. In the first O site, O(1) is bonded in a distorted linear geometry to one Sr(1), one Eu(1), and two equivalent Ti(1) atoms. In the second O site, O(2) is bonded in a distorted linear geometry to two equivalent Sr(1) and two equivalent Ti(1) atoms. In the third O site, O(3) is bonded in a distorted linear geometry to two equivalent Eu(1) and two equivalent Ti(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
