The crystal structure described by Sm2TiCuO6 is Orthorhombic Perovskite-derived structured and crystallizes in the monoclinic P2_1/c space group. Sm(1) is bonded in a 8-coordinate geometry to two equivalent O(1), three equivalent O(2), and three equivalent O(3) atoms. Ti(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form TiO6 octahedra that share corners with six equivalent Cu(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 33-36°. Cu(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form CuO6 octahedra that share corners with six equivalent Ti(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 33-36°. There are three inequivalent O sites. In the first O site, O(1) is bonded to two equivalent Sm(1), one Ti(1), and one Cu(1) atom to form distorted corner-sharing OSm2TiCu trigonal pyramids. In the second O site, O(2) is bonded in a 5-coordinate geometry to three equivalent Sm(1), one Ti(1), and one Cu(1) atom. In the third O site, O(3) is bonded in a 5-coordinate geometry to three equivalent Sm(1), one Ti(1), and one Cu(1) atom. is represented by the CIF card [CIF]
