Materials Data on VSnO3 by Materials Project
VSnO3 is Orthorhombic Perovskite structured and crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. V4+ is bonded in a distorted rectangular see-saw-like geometry to four O2- atoms. There are a spread of V–O bond distances ranging from 2.13–2.28 Å. Sn2+ is bonded to six O2- atoms to form corner-sharing SnO6 octahedra. The corner-sharing octahedra tilt angles range from 43–47°. There are a spread of Sn–O bond distances ranging from 2.09–2.14 Å. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a 3-coordinate geometry to one V4+ and two equivalent Sn2+ atoms. In the second O2- site, O2- is bonded to two equivalent V4+ and two equivalent Sn2+ atoms to form distorted corner-sharing OV2Sn2 trigonal pyramids.
