Materials Data on ZnSn2O5 by Materials Project
ZnSn2O5 is Antimony trioxide-derived structured and crystallizes in the triclinic P1 space group. The structure is three-dimensional. there are two inequivalent Zn2+ sites. In the first Zn2+ site, Zn2+ is bonded in a rectangular see-saw-like geometry to four O2- atoms. There are a spread of Zn–O bond distances ranging from 1.91–2.28 Å. In the second Zn2+ site, Zn2+ is bonded in a 4-coordinate geometry to four O2- atoms. There are a spread of Zn–O bond distances ranging from 1.91–2.49 Å. There are four inequivalent Sn4+ sites. In the first Sn4+ site, Sn4+ is bonded in a 5-coordinate geometry to five O2- atoms. There are a spread of Sn–O bond distances ranging from 1.97–2.20 Å. In the second Sn4+ site, Sn4+ is bonded in a 5-coordinate geometry to five O2- atoms. There are a spread of Sn–O bond distances ranging from 1.96–2.22 Å. In the third Sn4+ site, Sn4+ is bonded to five O2- atoms to form a mixture of distorted edge and corner-sharing SnO5 trigonal bipyramids. There are a spread of Sn–O bond distances ranging from 1.94–2.20 Å. In the fourth Sn4+ site, Sn4+ is bonded to five O2- atoms to form a mixture of distorted edge and corner-sharing SnO5 trigonal bipyramids. There are a spread of Sn–O bond distances ranging from 1.93–2.21 Å. There are ten inequivalent O2- sites. In the first O2- site, O2- is bonded in a trigonal planar geometry to one Zn2+ and two Sn4+ atoms. In the second O2- site, O2- is bonded in a trigonal planar geometry to one Zn2+ and two Sn4+ atoms. In the third O2- site, O2- is bonded in a trigonal non-coplanar geometry to three Sn4+ atoms. In the fourth O2- site, O2- is bonded in a trigonal non-coplanar geometry to three Sn4+ atoms. In the fifth O2- site, O2- is bonded in a trigonal non-coplanar geometry to three Sn4+ atoms. In the sixth O2- site, O2- is bonded in a trigonal non-coplanar geometry to three Sn4+ atoms. In the seventh O2- site, O2- is bonded in a bent 120 degrees geometry to one Zn2+ and one Sn4+ atom. In the eighth O2- site, O2- is bonded in a bent 120 degrees geometry to one Zn2+ and one Sn4+ atom. In the ninth O2- site, O2- is bonded in a distorted trigonal non-coplanar geometry to two equivalent Zn2+ and one Sn4+ atom. In the tenth O2- site, O2- is bonded in a trigonal non-coplanar geometry to two equivalent Zn2+ and one Sn4+ atom.
