Title: Materials Data on Na3(CoO2)4 by Materials Project

Abstract

Na3(CoO2)4 crystallizes in the orthorhombic Pmn2_1 space group. The structure is three-dimensional. there are three inequivalent Na1+ sites. In the first Na1+ site, Na1+ is bonded in a 6-coordinate geometry to six O2- atoms. There are four shorter (2.38 Å) and two longer (2.48 Å) Na–O bond lengths. In the second Na1+ site, Na1+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Na–O bond distances ranging from 2.30–2.40 Å. In the third Na1+ site, Na1+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Na–O bond distances ranging from 2.32–2.57 Å. There are four inequivalent Co+3.25+ sites. In the first Co+3.25+ site, Co+3.25+ is bonded to six O2- atoms to form edge-sharing CoO6 octahedra. There are a spread of Co–O bond distances ranging from 1.89–1.94 Å. In the second Co+3.25+ site, Co+3.25+ is bonded to six O2- atoms to form edge-sharing CoO6 octahedra. There are a spread of Co–O bond distances ranging from 1.91–1.95 Å. In the third Co+3.25+ site, Co+3.25+ is bonded to six O2- atoms to form edge-sharing CoO6 octahedra. There are a spread of Co–O bond distances ranging from 1.90–1.93 Å.

The corner-sharing octahedral tilt angles are 47°. In the sixth O2- site, O2- is bonded to two equivalent Na1+ and three Co+3.25+ atoms to form distorted ONa2Co3 square pyramids that share corners with four equivalent ONa3Co3 octahedra, corners with two equivalent ONa2Co3 square pyramids, edges with three ONa3Co3 octahedra, and edges with five ONa2Co3 square pyramids. The corner-sharing octahedra tilt angles range from 1–49°.
