The material structure described by Sr2TmBiO6 is Orthorhombic Perovskite-derived structured and crystallizes in the monoclinic P2_1/c space group. Sr(1) is bonded in a 8-coordinate geometry to two equivalent O(1), three equivalent O(2), and three equivalent O(3) atoms. Tm(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form TmO6 octahedra that share corners with six equivalent Bi(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 28-30°. Bi(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form BiO6 octahedra that share corners with six equivalent Tm(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 28-30°. There are three inequivalent O sites. In the first O site, O(1) is bonded to two equivalent Sr(1), one Tm(1), and one Bi(1) atom to form distorted corner-sharing OSr2TmBi tetrahedra. In the second O site, O(2) is bonded in a 5-coordinate geometry to three equivalent Sr(1), one Tm(1), and one Bi(1) atom. In the third O site, O(3) is bonded in a 5-coordinate geometry to three equivalent Sr(1), one Tm(1), and one Bi(1) atom. is represented by the CIF file [CIF]
