Title: Materials Data on MgH12SeO10 by Materials Project

Abstract

Mg(H2O)6MgH12(SeO7)2 crystallizes in the monoclinic C2/c space group. The structure is one-dimensional and consists of four magnesium;hexahydrate molecules and four MgH12(SeO7)2 ribbons oriented in the (0, 1, 0) direction. In each MgH12(SeO7)2 ribbon, Mg2+ is bonded in an octahedral geometry to six O2- atoms. There are a spread of Mg–O bond distances ranging from 2.06–2.12 Å. There are six inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.98 Å. In the second H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.99 Å. In the third H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.99 Å. In the fourth H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.98 Å. In the fifth H1+ site, H1+ is bonded in a single-bond geometry to two O2- atoms. There is one shorter (0.99 Å) and one longer (1.76 Å) H–O bond length. In the sixth H1+ site, H1+ is bonded in a single-bond geometry to two O2- atoms.more » There is one shorter (1.00 Å) and one longer (1.71 Å) H–O bond length. Se6+ is bonded in a tetrahedral geometry to four O2- atoms. There are a spread of Se–O bond distances ranging from 1.67–1.69 Å. There are seven inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted single-bond geometry to one Se6+ atom. In the second O2- site, O2- is bonded in a single-bond geometry to one Se6+ atom. In the third O2- site, O2- is bonded in a single-bond geometry to one Se6+ atom. In the fourth O2- site, O2- is bonded in a distorted trigonal planar geometry to one Mg2+ and two H1+ atoms. In the fifth O2- site, O2- is bonded in a distorted water-like geometry to one Mg2+ and two H1+ atoms. In the sixth O2- site, O2- is bonded in a distorted trigonal planar geometry to one Mg2+ and two H1+ atoms. In the seventh O2- site, O2- is bonded in a 3-coordinate geometry to two H1+ and one Se6+ atom.« less
