Materials Data on Sr2SnO4 by Materials Project
Sr2SnO4 crystallizes in the orthorhombic Pccn space group. The structure is three-dimensional. Sr2+ is bonded in a 1-coordinate geometry to seven O2- atoms. There are a spread of Sr–O bond distances ranging from 2.43–2.96 Å. Sn4+ is bonded to six O2- atoms to form corner-sharing SnO6 octahedra. The corner-sharing octahedra tilt angles range from 1–21°. There are four shorter (2.08 Å) and two longer (2.11 Å) Sn–O bond lengths. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted rectangular see-saw-like geometry to three equivalent Sr2+ and one Sn4+ atom. In the second O2- site, O2- is bonded to four equivalent Sr2+ and two equivalent Sn4+ atoms to form a mixture of distorted corner and edge-sharing OSr4Sn2 octahedra. The corner-sharing octahedral tilt angles are 0°. In the third O2- site, O2- is bonded in a 6-coordinate geometry to four equivalent Sr2+ and two equivalent Sn4+ atoms.
