Materials Data on BeH8SeO8 by Materials Project
BeH8SeO8 crystallizes in the orthorhombic Cmce space group. The structure is three-dimensional. Be2+ is bonded in a tetrahedral geometry to four O2- atoms. There is one shorter (1.61 Å) and three longer (1.63 Å) Be–O bond length. There are four inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a distorted linear geometry to two O2- atoms. There is one shorter (1.01 Å) and one longer (1.64 Å) H–O bond length. In the second H1+ site, H1+ is bonded in a distorted single-bond geometry to two O2- atoms. There is one shorter (1.00 Å) and one longer (1.67 Å) H–O bond length. In the third H1+ site, H1+ is bonded in a distorted single-bond geometry to two O2- atoms. There is one shorter (1.00 Å) and one longer (1.67 Å) H–O bond length. In the fourth H1+ site, H1+ is bonded in a distorted linear geometry to two O2- atoms. There is one shorter (1.00 Å) and one longer (1.63 Å) H–O bond length. Se6+ is bonded in a tetrahedral geometry to four O2- atoms. There is two shorter (1.67 Å) and two longer (1.68 Å) Se–O bond length. There are five inequivalent O2- sites. In the first O2- site, O2- is bonded in a trigonal planar geometry to one Be2+ and two equivalent H1+ atoms. In the second O2- site, O2- is bonded in a trigonal planar geometry to one Be2+ and two equivalent H1+ atoms. In the third O2- site, O2- is bonded in a trigonal planar geometry to one Be2+ and two H1+ atoms. In the fourth O2- site, O2- is bonded in a distorted trigonal planar geometry to two H1+ and one Se6+ atom. In the fifth O2- site, O2- is bonded in a trigonal planar geometry to two H1+ and one Se6+ atom.
