MgSmTiO3 crystallizes in the trigonal R3m space group. Mg(1) is bonded in a distorted T-shaped geometry to three equivalent O(1) atoms. Sm(1) is bonded in a 3-coordinate geometry to three equivalent O(1) atoms. Ti(1) is bonded to six equivalent O(1) atoms to form corner-sharing TiO6 octahedra. The corner-sharing octahedral tilt angles are 3°. O(1) is bonded in a distorted rectangular see-saw-like geometry to one Mg(1), one Sm(1), and two equivalent Ti(1) atoms.
MgSmTiO3 crystallizes in the trigonal R3m space group. Mg(1) is bonded in a distorted T-shaped geometry to three equivalent O(1) atoms. All Mg(1)-O(1) bond lengths are 1.99 Å. Sm(1) is bonded in a 3-coordinate geometry to three equivalent O(1) atoms. All Sm(1)-O(1) bond lengths are 2.30 Å. Ti(1) is bonded to six equivalent O(1) atoms to form corner-sharing TiO6 octahedra. The corner-sharing octahedral tilt angles are 3°. There are three shorter (2.13 Å) and three longer (2.24 Å) Ti(1)-O(1) bond lengths. O(1) is bonded in a distorted rectangular see-saw-like geometry to one Mg(1), one Sm(1), and two equivalent Ti(1) atoms.
