Materials Data on Al(SnO2)2 by Materials Project

Abstract

Al(SnO2)2 crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. Al3+ is bonded in a square co-planar geometry to four O2- atoms. All Al–O bond lengths are 1.85 Å. There are two inequivalent Sn+2.50+ sites. In the first Sn+2.50+ site, Sn+2.50+ is bonded in a square co-planar geometry to four O2- atoms. There are two shorter (2.18 Å) and two longer (2.29 Å) Sn–O bond lengths. In the second Sn+2.50+ site, Sn+2.50+ is bonded in a square co-planar geometry to four O2- atoms. There are two shorter (2.09 Å) and two longer (2.22 Å) Sn–O bond lengths. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted trigonal non-coplanar geometry to one Al3+ and two Sn+2.50+ atoms. In the second O2- site, O2- is bonded in a distorted trigonal non-coplanar geometry to one Al3+ and two Sn+2.50+ atoms.
