Materials Data on TlGeF3 by Materials Project

TlGeF3 is Potassium chlorate structured and crystallizes in the monoclinic P2_1/m space group. The structure is three-dimensional. Tl1+ is bonded in a 9-coordinate geometry to nine F1- atoms. There are a spread of Tl–F bond distances ranging from 2.89–3.53 Å. Ge2+ is bonded in a distorted T-shaped geometry to three F1- atoms. All Ge–F bond lengths are 1.88 Å. There are two inequivalent F1- sites. In the first F1- site, F1- is bonded in a distorted single-bond geometry to three equivalent Tl1+ and one Ge2+ atom. In the second F1- site, F1- is bonded in a single-bond geometry to three equivalent Tl1+ and one Ge2+ atom.

Materials Data on TlGeF3 by Materials Project

TlGeF3 crystallizes in the triclinic P1 space group. The structure is three-dimensional. Tl1+ is bonded in a 8-coordinate geometry to eight F1- atoms. There are a spread of Tl–F bond distances ranging from 2.76–3.48 Å. Ge2+ is bonded in a distorted T-shaped geometry to three F1- atoms. There is two shorter (1.90 Å) and one longer (1.91 Å) Ge–F bond length. There are three inequivalent F1- sites. In the first F1- site, F1- is bonded in a distorted single-bond geometry to three equivalent Tl1+ and one Ge2+ atom. In the second F1- site, F1- is bonded in a distorted single-bond geometry to two equivalent Tl1+ and one Ge2+ atom. In the third F1- site, F1- is bonded in a distorted single-bond geometry to three equivalent Tl1+ and one Ge2+ atom.
