Materials Data on Ca(SeO3)2 by Materials Project
Ca(SeO3)2 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. Ca2+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Ca–O bond distances ranging from 2.35–2.56 Å. There are two inequivalent Se5+ sites. In the first Se5+ site, Se5+ is bonded in a tetrahedral geometry to four O2- atoms. There are a spread of Se–O bond distances ranging from 1.65–1.76 Å. In the second Se5+ site, Se5+ is bonded in a distorted trigonal non-coplanar geometry to three O2- atoms. There are a spread of Se–O bond distances ranging from 1.67–1.98 Å. There are six inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted trigonal planar geometry to two equivalent Ca2+ and one Se5+ atom. In the second O2- site, O2- is bonded in a bent 120 degrees geometry to one Ca2+ and one Se5+ atom. In the third O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Ca2+ and one Se5+ atom. In the fourth O2- site, O2- is bonded in a bent 120 degrees geometry to one Ca2+ and one Se5+ atom. In the fifth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Ca2+ and one Se5+ atom. In the sixth O2- site, O2- is bonded in a bent 150 degrees geometry to two Se5+ atoms.
