Materials Data on Sn(SeO3)2 by Materials Project

Abstract

Sn(SeO3)2 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. Sn4+ is bonded in an octahedral geometry to six O2- atoms. There are four shorter (2.08 Å) and two longer (2.10 Å) Sn–O bond lengths. Se4+ is bonded in a trigonal non-coplanar geometry to three O2- atoms. There is one shorter (1.73 Å) and two longer (1.74 Å) Se–O bond length. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Sn4+ and one Se4+ atom. In the second O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Sn4+ and one Se4+ atom. In the third O2- site, O2- is bonded in a bent 120 degrees geometry to one Sn4+ and one Se4+ atom.
