SrDyLaSnO6 is Orthorhombic Perovskite-derived structured and crystallizes in the orthorhombic Pnnn space group. There are two inequivalent Sr sites. In the first Sr site, Sr(1) is bonded in a distorted square co-planar geometry to four equivalent O(3) atoms. In the second Sr site, Sr(2) is bonded in a distorted square co-planar geometry to four equivalent O(1) and four equivalent O(3) atoms. Dy(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form DyO6 octahedra that share corners with six equivalent Sn(1)O6 octahedra and faces with two equivalent La(2)O12 cuboctahedra. The corner-sharing octahedral tilt angles range from 25-30°. There are two inequivalent La sites. In the first La site, La(1) is bonded in a distorted square co-planar geometry to four equivalent O(2) atoms. In the second La site, La(2) is bonded to four equivalent O(1), four equivalent O(2), and four equivalent O(3) atoms to form LaO12 cuboctahedra that share faces with four equivalent Dy(1)O6 octahedra and faces with four equivalent Sn(1)O6 octahedra. Sn(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form SnO6 octahedra that share corners with six equivalent Dy(1)O6 octahedra and faces with two equivalent La(2)O12 cuboctahedra. The corner-sharing octahedral tilt angles range from 25-30°. There are three inequivalent O sites.
