EuTi4SnO12 crystallizes in the orthorhombic Amm2 space group. Eu(1) is bonded in a 10-coordinate geometry to two equivalent O(3), four equivalent O(1), and four equivalent O(5) atoms. Ti(1) is bonded to one O(2), one O(3), one O(4), one O(5), and two equivalent O(1) atoms to form corner-sharing TiO6 octahedra. The corner-sharing octahedral tilt angles range from 18-45°. Sn(1) is bonded in a 4-coordinate geometry to two equivalent O(2) and two equivalent O(4) atoms. There are five inequivalent O sites. In the first O site, O(1) is bonded in a distorted T-shaped geometry to one Eu(1) and two equivalent Ti(1) atoms. In the second O site, O(2) is bonded in a trigonal planar geometry to two equivalent Ti(1) and one Sn(1) atom. In the third O site, O(3) is bonded in a 2-coordinate geometry to one Eu(1) and two equivalent Ti(1) atoms. In the fourth O site, O(4) is bonded in a distorted trigonal non-coplanar geometry to two equivalent Ti(1) and one Sn(1) atom. In the fifth O site, O(5) is bonded in a 2-coordinate geometry to two equivalent Eu(1) and two equivalent Ti(1) atoms.
