Title: Materials Data on Na5ReO6 by Materials Project

Abstract

Na5ReO6 is High Pressure (4-7GPa) Tellurium-derived structured and crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. there are three inequivalent Na1+ sites. In the first Na1+ site, Na1+ is bonded to six O2- atoms to form NaO6 octahedra that share corners with two equivalent ReO6 octahedra, corners with four equivalent NaO6 octahedra, edges with two equivalent ReO6 octahedra, and edges with ten NaO6 octahedra. The corner-sharing octahedra tilt angles range from 1–22°. There are a spread of Na–O bond distances ranging from 2.36–2.65 Å. In the second Na1+ site, Na1+ is bonded to six O2- atoms to form distorted NaO6 octahedra that share corners with six NaO6 octahedra, edges with three equivalent ReO6 octahedra, and edges with nine NaO6 octahedra. The corner-sharing octahedra tilt angles range from 19–22°. There are a spread of Na–O bond distances ranging from 2.35–2.41 Å. In the third Na1+ site, Na1+ is bonded to six O2- atoms to form distorted NaO6 octahedra that share corners with two equivalent ReO6 octahedra, corners with four equivalent NaO6 octahedra, edges with two equivalent ReO6 octahedra, and edges with ten NaO6 octahedra. The corner-sharing octahedra tilt angles range from 0–19°. There are four shorter (2.32 Å)more » and two longer (2.80 Å) Na–O bond lengths. Re7+ is bonded to six O2- atoms to form ReO6 octahedra that share corners with six NaO6 octahedra and edges with twelve NaO6 octahedra. The corner-sharing octahedra tilt angles range from 0–1°. There is two shorter (1.91 Å) and four longer (1.93 Å) Re–O bond length. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a 6-coordinate geometry to five Na1+ and one Re7+ atom. In the second O2- site, O2- is bonded to five Na1+ and one Re7+ atom to form a mixture of distorted corner and edge-sharing ONa5Re octahedra. The corner-sharing octahedra tilt angles range from 0–16°.« less
