Materials Data on MnH2(SeO4)2 by Materials Project
MnH2(SeO4)2 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. Mn2+ is bonded to six O2- atoms to form MnO6 octahedra that share corners with six SeO4 tetrahedra. There are a spread of Mn–O bond distances ranging from 2.16–2.23 Å. There are two 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 1.00 Å. In the second H1+ site, H1+ is bonded in a distorted single-bond geometry to two O2- atoms. There is one shorter (1.01 Å) and one longer (1.69 Å) H–O bond length. There are two inequivalent Se6+ sites. In the first Se6+ site, Se6+ is bonded to four O2- atoms to form SeO4 tetrahedra that share corners with three equivalent MnO6 octahedra. The corner-sharing octahedra tilt angles range from 43–52°. There are a spread of Se–O bond distances ranging from 1.64–1.76 Å. In the second Se6+ site, Se6+ is bonded to four O2- atoms to form SeO4 tetrahedra that share corners with three equivalent MnO6 octahedra. The corner-sharing octahedra tilt angles range from 40–46°. There are a spread of Se–O bond distances ranging from 1.65–1.76 Å. There are eight inequivalent O2- sites. In the first O2- site, O2- is bonded in a water-like geometry to one H1+ and one Se6+ atom. In the second O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Mn2+ and one Se6+ atom. In the third O2- site, O2- is bonded in a bent 150 degrees geometry to one Mn2+ and one Se6+ atom. In the fourth O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Mn2+ and one Se6+ atom. In the fifth O2- site, O2- is bonded in a distorted water-like geometry to one H1+ and one Se6+ atom. In the sixth O2- site, O2- is bonded in a distorted trigonal planar geometry to one Mn2+, one H1+, and one Se6+ atom. In the seventh O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Mn2+ and one Se6+ atom. In the eighth O2- site, O2- is bonded in a bent 120 degrees geometry to one Mn2+ and one Se6+ atom.
