Materials Data on Na2RuO3 by Materials Project
Na2RuO3 is Caswellsilverite-like structured and crystallizes in the monoclinic C2/c 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 six NaO6 octahedra, edges with six NaO6 octahedra, and edges with six RuO6 octahedra. The corner-sharing octahedra tilt angles range from 14–16°. There are two shorter (2.30 Å) and four longer (2.31 Å) Na–O bond lengths. In the second Na1+ site, Na1+ is bonded to six O2- atoms to form distorted NaO6 octahedra that share corners with two equivalent NaO6 octahedra, corners with four RuO6 octahedra, edges with four RuO6 octahedra, and edges with eight NaO6 octahedra. The corner-sharing octahedra tilt angles range from 11–16°. There are a spread of Na–O bond distances ranging from 2.30–2.57 Å. In the third Na1+ site, Na1+ is bonded to six O2- atoms to form NaO6 octahedra that share corners with two equivalent NaO6 octahedra, corners with four RuO6 octahedra, edges with four RuO6 octahedra, and edges with eight NaO6 octahedra. The corner-sharing octahedra tilt angles range from 12–14°. There are a spread of Na–O bond distances ranging from 2.28–2.49 Å. There are two inequivalent Ru4+ sites. In the first Ru4+ site, Ru4+ is bonded to six O2- atoms to form RuO6 octahedra that share corners with six NaO6 octahedra, edges with three equivalent RuO6 octahedra, and edges with nine NaO6 octahedra. The corner-sharing octahedra tilt angles range from 12–13°. There are a spread of Ru–O bond distances ranging from 2.04–2.09 Å. In the second Ru4+ site, Ru4+ is bonded to six O2- atoms to form RuO6 octahedra that share corners with six NaO6 octahedra, edges with three equivalent RuO6 octahedra, and edges with nine NaO6 octahedra. The corner-sharing octahedra tilt angles range from 11–12°. There are a spread of Ru–O bond distances ranging from 2.04–2.08 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded to four Na1+ and two Ru4+ atoms to form a mixture of edge and corner-sharing ONa4Ru2 octahedra. The corner-sharing octahedra tilt angles range from 0–11°. In the second O2- site, O2- is bonded to four Na1+ and two Ru4+ atoms to form a mixture of distorted edge and corner-sharing ONa4Ru2 octahedra. The corner-sharing octahedra tilt angles range from 0–11°. In the third O2- site, O2- is bonded to four Na1+ and two Ru4+ atoms to form a mixture of edge and corner-sharing ONa4Ru2 octahedra. The corner-sharing octahedra tilt angles range from 0–10°.
