EuTiO14 crystallizes in the cubic Fd-3m space group. Eu(1) is bonded to four equivalent O(1) and twelve equivalent O(2) atoms to form EuO16 tetrahedra that share corners with four equivalent Eu(1)O16 tetrahedra and faces with four equivalent Ti(1)O12 cuboctahedra. Ti(1) is bonded to twelve equivalent O(2) atoms to form TiO12 cuboctahedra that share faces with four equivalent Eu(1)O16 tetrahedra. There are two inequivalent O sites. In the first O site, O(2) is bonded in a 6-coordinate geometry to one Eu(1), one Ti(1), and four equivalent O(2) atoms. In the second O site, O(1) is bonded in a linear geometry to two equivalent Eu(1) atoms.

Eu(1) is bonded to four equivalent O(1) and twelve equivalent O(2) atoms to form EuO16 tetrahedra that share corners with four equivalent Eu(1)O16 tetrahedra and faces with four equivalent Ti(1)O12 cuboctahedra. All Eu(1)-O(1) bond lengths are 2.31 Å. All Eu(1)-O(2) bond lengths are 2.91 Å. Ti(1) is bonded to twelve equivalent O(2) atoms to form TiO12 cuboctahedra that share faces with four equivalent Eu(1)O16 tetrahedra. All Ti(1)-O(2) bond lengths are 2.25 Å. There are two inequivalent O sites. In the first O site, O(2) is bonded in a 6-coordinate geometry to one Eu(1), one Ti(1), and four equivalent O(2) atoms. There are two shorter (1.85 Å) and two longer (1.99 Å) O(2)-O(2) bond lengths. In the second O site, O(1) is bonded in a linear geometry to two equivalent Eu(1) atoms.
