Materials Data on SrH2(SeO3)2 by Materials Project
SrH2(SeO3)2 crystallizes in the triclinic P-1 space group. The structure is two-dimensional and consists of one SrH2(SeO3)2 sheet oriented in the (0, 0, 1) direction. Sr2+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Sr–O bond distances ranging from 2.55–2.88 Å. There are two inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a single-bond geometry to two O2- atoms. There is one shorter (1.01 Å) and one longer (1.74 Å) H–O bond length. In the second H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 1.00 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 1.69–1.83 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 1.69–1.85 Å. There are six inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted single-bond geometry to one H1+ and one Se4+ atom. In the second O2- site, O2- is bonded in a distorted single-bond geometry to one Sr2+, one H1+, and one Se4+ atom. In the third O2- site, O2- is bonded in a distorted trigonal planar geometry to two equivalent Sr2+ and one Se4+ atom. In the fourth O2- site, O2- is bonded in a 2-coordinate geometry to two equivalent Sr2+ and one Se4+ atom. In the fifth O2- site, O2- is bonded in a 1-coordinate geometry to one Sr2+, one H1+, and one Se4+ atom. In the sixth O2- site, O2- is bonded in a 3-coordinate geometry to two equivalent Sr2+ and one Se4+ atom.
