Materials Data on Zn(SnO2)2 by Materials Project

Abstract

ZnSn2O4 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Zn2+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Zn–O bond distances ranging from 2.70–2.82 Å. There are two inequivalent Sn3+ sites. In the first Sn3+ site, Sn3+ is bonded to six O2- atoms to form a mixture of corner and edge-sharing SnO6 octahedra. The corner-sharing octahedra tilt angles range from 50–52°. There are a spread of Sn–O bond distances ranging from 2.15–2.24 Å. In the second Sn3+ site, Sn3+ is bonded to six O2- atoms to form a mixture of corner and edge-sharing SnO6 octahedra. The corner-sharing octahedra tilt angles range from 50–52°. There are a spread of Sn–O bond distances ranging from 2.15–2.20 Å. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a 5-coordinate geometry to two equivalent Zn2+ and three equivalent Sn3+ atoms. In the second O2- site, O2- is bonded in a 5-coordinate geometry to two equivalent Zn2+ and three Sn3+ atoms. In the third O2- site, O2- is bonded to two equivalent Zn2+ and three equivalent Sn3+ atoms to form distorted edge-sharing OZn2Sn3 square pyramids. In the fourth O2- site, O2- is bonded in a trigonal planar geometry to three Sn3+ atoms.
