The compound described by NaEuTi4O12 crystallizes in the orthorhombic Amm2 space group. Na(1) is bonded in a 4-coordinate geometry to two equivalent O(3) and two equivalent O(5) atoms. Eu(1) is bonded in a 8-coordinate geometry to two equivalent O(2), four equivalent O(1), and four equivalent O(4) 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 14-28°. There are five inequivalent O sites. In the first O site, O(1) is bonded in a 3-coordinate geometry to one Eu(1) and two equivalent Ti(1) atoms. In the second O site, O(2) is bonded in a 3-coordinate geometry to one Eu(1) and two equivalent Ti(1) atoms. In the third O site, O(3) is bonded in a distorted T-shaped geometry to one Na(1) and two equivalent Ti(1) atoms. In the fourth O site, O(4) is bonded in a 4-coordinate geometry to two equivalent Eu(1) and two equivalent Ti(1) atoms. In the fifth O site, O(5) is bonded in a distorted T-shaped geometry to one Na(1) and two equivalent Ti(1) atoms. is represented by the CIF card [CIF]
