Title: Materials Data on Na2Te2H4O7 by Materials Project

Abstract

Na2H4Te2O7 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 five O2- atoms to form edge-sharing NaO5 trigonal bipyramids. There are a spread of Na–O bond distances ranging from 2.40–2.46 Å. In the second Na1+ site, Na1+ is bonded to six O2- atoms to form distorted edge-sharing NaO6 octahedra. There are a spread of Na–O bond distances ranging from 2.37–2.61 Å. There are four 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 single-bond geometry to one O2- atom. The H–O bond length is 1.00 Å. In the third H1+ site, H1+ is bonded in a single-bond geometry to two O2- atoms. There is one shorter (1.00 Å) and one longer (1.75 Å) H–O bond length. In the fourth H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.99 Å. There are two inequivalent Te4+ sites. In the first Te4+ site, Te4+ is bonded in a distortedmore » see-saw-like geometry to four O2- atoms. There are a spread of Te–O bond distances ranging from 1.88–2.50 Å. In the second Te4+ site, Te4+ is bonded in a distorted see-saw-like geometry to four O2- atoms. There are a spread of Te–O bond distances ranging from 1.87–2.17 Å. There are seven inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted rectangular see-saw-like geometry to two equivalent Na1+ and two equivalent Te4+ atoms. In the second O2- site, O2- is bonded to two equivalent Na1+ and two equivalent Te4+ atoms to form distorted edge-sharing ONa2Te2 tetrahedra. In the third O2- site, O2- is bonded in a distorted trigonal planar geometry to one Na1+ and two Te4+ atoms. In the fourth O2- site, O2- is bonded in a 2-coordinate geometry to one Na1+, one H1+, and one Te4+ atom. In the fifth O2- site, O2- is bonded in a distorted water-like geometry to one Na1+ and one Te4+ atom. In the sixth O2- site, O2- is bonded in a distorted water-like geometry to two equivalent Na1+ and two H1+ atoms. In the seventh O2- site, O2- is bonded in a distorted water-like geometry to two equivalent Na1+ and two H1+ atoms.« less
