Materials Data on SrMo2Se2O11 by Materials Project
SrMo2Se2O11 crystallizes in the triclinic P-1 space group. The structure is two-dimensional and consists of one SrMo2Se2O11 sheet oriented in the (1, 0, 0) direction. Sr2+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Sr–O bond distances ranging from 2.55–2.75 Å. There are two inequivalent Mo6+ sites. In the first Mo6+ site, Mo6+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Mo–O bond distances ranging from 1.74–2.35 Å. In the second Mo6+ site, Mo6+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Mo–O bond distances ranging from 1.74–2.32 Å. There are two inequivalent Se4+ sites. In the first Se4+ site, Se4+ is bonded in a distorted trigonal non-coplanar geometry to three O2- atoms. There are a spread of Se–O bond distances ranging from 1.68–1.78 Å. In the second Se4+ site, Se4+ is bonded in a distorted trigonal non-coplanar geometry to three O2- atoms. There are a spread of Se–O bond distances ranging from 1.68–1.78 Å. There are eleven inequivalent O2- sites. In the first O2- site, O2- is bonded in a single-bond geometry to one Mo6+ atom. In the second O2- site, O2- is bonded in a distorted single-bond geometry to one Sr2+ and one Mo6+ atom. In the third O2- site, O2- is bonded in a linear geometry to two Mo6+ atoms. In the fourth O2- site, O2- is bonded in a 3-coordinate geometry to one Sr2+, one Mo6+, and one Se4+ atom. In the fifth O2- site, O2- is bonded in a distorted trigonal planar geometry to two equivalent Mo6+ and one Se4+ atom. In the sixth O2- site, O2- is bonded in a single-bond geometry to one Mo6+ atom. In the seventh O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Sr2+ and one Mo6+ atom. In the eighth O2- site, O2- is bonded in a 3-coordinate geometry to one Sr2+, one Mo6+, and one Se4+ atom. In the ninth O2- site, O2- is bonded in a distorted trigonal planar geometry to two equivalent Mo6+ and one Se4+ atom. In the tenth O2- site, O2- is bonded in a 3-coordinate geometry to two equivalent Sr2+ and one Se4+ atom. In the eleventh O2- site, O2- is bonded in a 3-coordinate geometry to two equivalent Sr2+ and one Se4+ atom.
