SmYO3 is Orthorhombic Perovskite structured and crystallizes in the orthorhombic Pna2_1 space group. Sm(1) is bonded in a 6-coordinate geometry to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms. Y(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form corner-sharing YO6 octahedra. The corner-sharing octahedral tilt angles are 47°. There are three inequivalent O sites. In the first O site, O(1) is bonded to two equivalent Sm(1) and two equivalent Y(1) atoms to form a mixture of distorted corner and edge-sharing OSm2Y2 tetrahedra. In the second O site, O(2) is bonded to two equivalent Sm(1) and two equivalent Y(1) atoms to form a mixture of distorted corner and edge-sharing OSm2Y2 tetrahedra. In the third O site, O(3) is bonded to two equivalent Sm(1) and two equivalent Y(1) atoms to form a mixture of distorted corner and edge-sharing OSm2Y2 trigonal pyramids.
