Materials Data on Sr2SnO4 by Materials Project
Sr2SnO4 is Orthorhombic Perovskite-like structured and crystallizes in the orthorhombic Cmce space group. The structure is three-dimensional. Sr2+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Sr–O bond distances ranging from 2.42–2.93 Å. Sn4+ is bonded to six O2- atoms to form corner-sharing SnO6 octahedra. The corner-sharing octahedral tilt angles are 15°. There are two shorter (2.08 Å) and four longer (2.09 Å) Sn–O bond lengths. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded to four equivalent Sr2+ and one Sn4+ atom to form a mixture of distorted edge and corner-sharing OSr4Sn square pyramids. In the second O2- site, O2- is bonded in a 6-coordinate geometry to four equivalent Sr2+ and two equivalent Sn4+ atoms.
