Title: Materials Data on Na6NiO4 by Materials Project

Abstract

Na6NiO4 crystallizes in the monoclinic Cc space group. The structure is three-dimensional. there are six inequivalent Na1+ sites. In the first Na1+ site, Na1+ is bonded in a 4-coordinate geometry to four O2- atoms. There are a spread of Na–O bond distances ranging from 2.33–2.58 Å. In the second Na1+ site, Na1+ is bonded in a 5-coordinate geometry to five O2- atoms. There are a spread of Na–O bond distances ranging from 2.34–2.75 Å. In the third Na1+ site, Na1+ is bonded to four O2- atoms to form distorted NaO4 trigonal pyramids that share corners with two equivalent NiO4 tetrahedra, corners with six NaO4 trigonal pyramids, and an edgeedge with one NiO4 tetrahedra. There are a spread of Na–O bond distances ranging from 2.36–2.56 Å. In the fourth Na1+ site, Na1+ is bonded in a 5-coordinate geometry to five O2- atoms. There are a spread of Na–O bond distances ranging from 2.35–2.72 Å. In the fifth Na1+ site, Na1+ is bonded in a 3-coordinate geometry to five O2- atoms. There are a spread of Na–O bond distances ranging from 2.34–2.75 Å. In the sixth Na1+ site, Na1+ is bonded to four O2- atoms to form distorted NaO4 trigonal pyramids thatmore » share corners with two equivalent NiO4 tetrahedra, corners with four equivalent NaO4 trigonal pyramids, and an edgeedge with one NiO4 tetrahedra. There are a spread of Na–O bond distances ranging from 2.35–2.55 Å. Ni2+ is bonded to four O2- atoms to form NiO4 tetrahedra that share corners with four NaO4 trigonal pyramids and edges with two NaO4 trigonal pyramids. There are a spread of Ni–O bond distances ranging from 1.98–2.06 Å. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a 6-coordinate geometry to seven Na1+ and one Ni2+ atom. In the second O2- site, O2- is bonded in a 8-coordinate geometry to seven Na1+ and one Ni2+ atom. In the third O2- site, O2- is bonded in a 7-coordinate geometry to six Na1+ and one Ni2+ atom. In the fourth O2- site, O2- is bonded in a 8-coordinate geometry to seven Na1+ and one Ni2+ atom.« less
