Materials Data on Sr2CuH2(SeO3)4 by Materials Project
Sr2CuH2(SeO3)4 crystallizes in the triclinic P-1 space group. The structure is three-dimensional. Sr2+ is bonded to seven O2- atoms to form distorted edge-sharing SrO7 pentagonal bipyramids. There are a spread of Sr–O bond distances ranging from 2.48–2.79 Å. Cu2+ is bonded in a distorted square co-planar geometry to four O2- atoms. There is two shorter (1.93 Å) and two longer (2.04 Å) Cu–O bond length. H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.97 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 1.69–1.84 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 1.66–1.99 Å. There are six inequivalent O2- sites. In the first O2- site, O2- is bonded in a 3-coordinate geometry to one Sr2+, one Cu2+, and one H1+ atom. In the second O2- site, O2- is bonded in a distorted trigonal non-coplanar geometry to two equivalent Sr2+ and one Se4+ atom. In the third O2- site, O2- is bonded in a single-bond geometry to one Se4+ atom. In the fourth O2- site, O2- is bonded in a 3-coordinate geometry to one Sr2+ and two Se4+ atoms. In the fifth O2- site, O2- is bonded in a 3-coordinate geometry to one Sr2+, one Cu2+, 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.
