Materials Data on TiF3 by Materials Project
TiF3 crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. Ti3+ is bonded in a distorted hexagonal planar geometry to six F1- atoms. There are two shorter (1.96 Å) and four longer (2.17 Å) Ti–F bond lengths. There are two inequivalent F1- sites. In the first F1- site, F1- is bonded in a linear geometry to two equivalent Ti3+ atoms. In the second F1- site, F1- is bonded in a linear geometry to two equivalent Ti3+ atoms.
