Materials Data on K2TiF5 by Materials Project
Abstract
K2TiF5 crystallizes in the orthorhombic Pbcn space group. The structure is three-dimensional. there are five inequivalent K1+ sites. In the first K1+ site, K1+ is bonded in a 8-coordinate geometry to eight F1- atoms. There are a spread of K–F bond distances ranging from 2.68–2.91 Å. In the second K1+ site, K1+ is bonded in a 10-coordinate geometry to ten F1- atoms. There are a spread of K–F bond distances ranging from 2.64–3.17 Å. In the third K1+ site, K1+ is bonded in a 11-coordinate geometry to eleven F1- atoms. There are a spread of K–F bond distances ranging from 2.70–3.26 Å. In the fourth K1+ site, K1+ is bonded in a 10-coordinate geometry to ten F1- atoms. There are a spread of K–F bond distances ranging from 2.74–3.19 Å. In the fifth K1+ site, K1+ is bonded in a 11-coordinate geometry to eleven F1- atoms. There are a spread of K–F bond distances ranging from 2.66–3.31 Å. There are two inequivalent Ti3+ sites. In the first Ti3+ site, Ti3+ is bonded to six F1- atoms to form corner-sharing TiF6 octahedra. The corner-sharing octahedra tilt angles range from 4–11°. There are a spread of Ti–F bond distances ranging from 1.92–2.06more »
