Materials Data on Na2TiF6 by Materials Project
Abstract
Na2TiF6 is zeta iron carbide-derived structured and crystallizes in the monoclinic C2 space group. The structure is three-dimensional. there are four inequivalent Na1+ sites. In the first Na1+ site, Na1+ is bonded to six F1- atoms to form NaF6 octahedra that share corners with four equivalent TiF6 octahedra, corners with six NaF6 octahedra, and an edgeedge with one TiF6 octahedra. The corner-sharing octahedra tilt angles range from 45–60°. There are a spread of Na–F bond distances ranging from 2.34–2.47 Å. In the second Na1+ site, Na1+ is bonded to six F1- atoms to form distorted NaF6 octahedra that share corners with two equivalent TiF6 octahedra, corners with six NaF6 octahedra, and edges with two equivalent TiF6 octahedra. The corner-sharing octahedra tilt angles range from 50–60°. There are a spread of Na–F bond distances ranging from 2.25–2.37 Å. In the third Na1+ site, Na1+ is bonded to six F1- atoms to form distorted NaF6 octahedra that share corners with two equivalent TiF6 octahedra, corners with six NaF6 octahedra, and edges with two equivalent TiF6 octahedra. The corner-sharing octahedra tilt angles range from 50–60°. There are a spread of Na–F bond distances ranging from 2.26–2.37 Å. In the fourth Na1+ site, Na1+more »
