Materials Data on KTiF4 by Materials Project
KTiF4 crystallizes in the triclinic P1 space group. The structure is three-dimensional. there are two inequivalent K1+ sites. In the first K1+ site, K1+ is bonded in a 5-coordinate geometry to five F1- atoms. There are one shorter (2.61 Å) and four longer (2.67 Å) K–F bond lengths. In the second K1+ site, K1+ is bonded in a 5-coordinate geometry to five F1- atoms. There are a spread of K–F bond distances ranging from 2.58–2.68 Å. There are two inequivalent Ti3+ sites. In the first Ti3+ site, Ti3+ is bonded to six F1- atoms to form a mixture of edge and corner-sharing TiF6 octahedra. The corner-sharing octahedral tilt angles are 3°. There are a spread of Ti–F bond distances ranging from 1.92–2.07 Å. In the second Ti3+ site, Ti3+ is bonded to six F1- atoms to form a mixture of edge and corner-sharing TiF6 octahedra. The corner-sharing octahedral tilt angles are 3°. There are a spread of Ti–F bond distances ranging from 1.92–2.07 Å. There are eight inequivalent F1- sites. In the first F1- site, F1- is bonded in a distorted trigonal planar geometry to one K1+ and two Ti3+ atoms. In the second F1- site, F1- is bonded in a 1-coordinate geometry to two equivalent K1+ and one Ti3+ atom. In the third F1- site, F1- is bonded in a 1-coordinate geometry to two equivalent K1+ and one Ti3+ atom. In the fourth F1- site, F1- is bonded in a linear geometry to two equivalent Ti3+ atoms. In the fifth F1- site, F1- is bonded in a linear geometry to two equivalent Ti3+ atoms. In the sixth F1- site, F1- is bonded in a 3-coordinate geometry to two equivalent K1+ and one Ti3+ atom. In the seventh F1- site, F1- is bonded in a 3-coordinate geometry to two equivalent K1+ and one Ti3+ atom. In the eighth F1- site, F1- is bonded in a distorted trigonal planar geometry to one K1+ and two Ti3+ atoms.
