Materials Data on Th(NF2)4 by Materials Project

Abstract

ThF4(NF)4 crystallizes in the triclinic P-1 space group. The structure is one-dimensional and consists of eight monofluoroamine molecules and one ThF4 ribbon oriented in the (1, 0, 0) direction. In the ThF4 ribbon, Th4+ is bonded in a 6-coordinate geometry to six F1- atoms. There are a spread of Th–F bond distances ranging from 2.11–2.40 Å. There are four inequivalent F1- sites. In the first F1- site, F1- is bonded in a single-bond geometry to one Th4+ atom. In the second F1- site, F1- is bonded in a bent 120 degrees geometry to two equivalent Th4+ atoms. In the third F1- site, F1- is bonded in a single-bond geometry to one Th4+ atom. In the fourth F1- site, F1- is bonded in a water-like geometry to two equivalent Th4+ atoms.
