The material structure described by Sr2SnO4 is (La,Ba)CuO4 structured and crystallizes in the tetragonal I4/mmm space group. Sr(1) is bonded in a 9-coordinate geometry to four equivalent O(2) and five equivalent O(1) atoms. Sn(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form corner-sharing SnO6 octahedra. The corner-sharing octahedra are not tilted. There are two inequivalent O sites. In the first O site, O(2) is bonded to four equivalent Sr(1) and two equivalent Sn(1) atoms to form OSr4Sn2 octahedra that share corners with two equivalent O(2)Sr4Sn2 octahedra, corners with twelve equivalent O(1)Sr5Sn octahedra, edges with two equivalent O(2)Sr4Sn2 octahedra, faces with four equivalent O(2)Sr4Sn2 octahedra, and faces with four equivalent O(1)Sr5Sn octahedra. The corner-sharing octahedral tilt angles range from 0-55°. In the second O site, O(1) is bonded to five equivalent Sr(1) and one Sn(1) atom to form distorted OSr5Sn octahedra that share corners with five equivalent O(1)Sr5Sn octahedra, corners with twelve equivalent O(2)Sr4Sn2 octahedra, edges with eight equivalent O(1)Sr5Sn octahedra, and faces with four equivalent O(2)Sr4Sn2 octahedra. The corner-sharing octahedral tilt angles range from 0-55°. is represented by the CIF file [CIF]
