Materials Data on Na3H5(SeO4)4 by Materials Project
Na3H5(SeO4)4 crystallizes in the triclinic P-1 space group. The structure is three-dimensional. there are two inequivalent Na1+ sites. In the first Na1+ site, Na1+ is bonded to six O2- atoms to form NaO6 octahedra that share a cornercorner with one NaO6 octahedra, corners with six SeO4 tetrahedra, and edges with two equivalent NaO6 octahedra. The corner-sharing octahedral tilt angles are 71°. There are a spread of Na–O bond distances ranging from 2.43–2.51 Å. In the second Na1+ site, Na1+ is bonded to six O2- atoms to form NaO6 octahedra that share corners with two equivalent NaO6 octahedra and corners with six SeO4 tetrahedra. The corner-sharing octahedral tilt angles are 71°. There are four shorter (2.44 Å) and two longer (2.58 Å) Na–O bond lengths. There are three 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 (1.72 Å) H–O bond length. In the second H1+ site, H1+ is bonded in a linear geometry to two equivalent O2- atoms. Both H–O bond lengths are 1.21 Å. In the third H1+ site, H1+ is bonded in a distorted linear geometry to two O2- atoms. There is one shorter (1.02 Å) and one longer (1.62 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 four NaO6 octahedra. The corner-sharing octahedra tilt angles range from 41–52°. There are a spread of Se–O bond distances ranging from 1.65–1.76 Å. In the second Se6+ site, Se6+ is bonded to four O2- atoms to form SeO4 tetrahedra that share corners with five NaO6 octahedra. The corner-sharing octahedra tilt angles range from 33–56°. There are a spread of Se–O bond distances ranging from 1.64–1.74 Å. There are eight inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted trigonal planar geometry to one Na1+, one H1+, and one Se6+ atom. In the second O2- site, O2- is bonded in a 3-coordinate geometry to two equivalent Na1+ and one Se6+ atom. In the third O2- site, O2- is bonded in a distorted trigonal planar geometry to one Na1+, one H1+, and one Se6+ atom. In the fourth O2- site, O2- is bonded in a distorted water-like geometry to one H1+ and one Se6+ atom. In the fifth O2- site, O2- is bonded in a distorted trigonal planar geometry to two equivalent Na1+ and one Se6+ atom. In the sixth O2- site, O2- is bonded in a trigonal planar geometry to two Na1+ and one Se6+ atom. In the seventh O2- site, O2- is bonded in a 1-coordinate geometry to one Na1+, one H1+, and one Se6+ atom. In the eighth O2- site, O2- is bonded in a distorted water-like geometry to one H1+ and one Se6+ atom.
