Materials Data on ThF4 by Materials Project
ThF4 crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. there are two inequivalent Th4+ sites. In the first Th4+ site, Th4+ is bonded in a 8-coordinate geometry to eight F1- atoms. There are a spread of Th–F bond distances ranging from 2.33–2.40 Å. In the second Th4+ site, Th4+ is bonded in a 8-coordinate geometry to eight F1- atoms. There are a spread of Th–F bond distances ranging from 2.30–2.38 Å. There are seven inequivalent F1- sites. In the first F1- site, F1- is bonded in a distorted bent 150 degrees geometry to two equivalent Th4+ atoms. In the second F1- site, F1- is bonded in a distorted linear geometry to two Th4+ atoms. In the third F1- site, F1- is bonded in a distorted linear geometry to two equivalent Th4+ atoms. In the fourth F1- site, F1- is bonded in a linear geometry to two Th4+ atoms. In the fifth F1- site, F1- is bonded in a bent 150 degrees geometry to two Th4+ atoms. In the sixth F1- site, F1- is bonded in a linear geometry to two equivalent Th4+ atoms. In the seventh F1- site, F1- is bonded in a distorted bent 150 degrees geometry to two Th4+ atoms.
