The material structure described by EuNdTi4O12 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. Nd(1) is bonded to two equivalent O(2), two equivalent O(3), four equivalent O(1), and four equivalent O(4) atoms to form distorted NdO12 cuboctahedra that share corners with four equivalent Nd(1)O12 cuboctahedra and faces with eight equivalent Ti(1)O6 octahedra. 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 TiO6 octahedra that share corners with six equivalent Ti(1)O6 octahedra and faces with two equivalent Nd(1)O12 cuboctahedra. The corner-sharing octahedral tilt angles range from 12-20°. There are five inequivalent O sites. In the first O site, O(1) is bonded in a 2-coordinate geometry to one Eu(1), one Nd(1), and two equivalent Ti(1) atoms. In the second O site, O(2) is bonded in a distorted T-shaped geometry to one Nd(1) and two equivalent Ti(1) atoms. In the third O site, O(3) is bonded in a distorted rectangular see-saw-like geometry to one Eu(1), one Nd(1), and two equivalent Ti(1) atoms. In the fourth O site, O(4) is bonded in a 3-coordinate geometry to two equivalent Nd(1) and two equivalent Ti(1) atoms. 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. is represented by the CIF card [CIF]
