Materials Data on Cs2TaAgF6 by Materials Project
(Cs)2AgTaF6 is Heusler structured and crystallizes in the monoclinic C2/m space group. The structure is zero-dimensional and consists of four cesium molecules, two silver molecules, and two TaF6 clusters. In each TaF6 cluster, Ta3+ is bonded in an octahedral geometry to six F1- atoms. All Ta–F bond lengths are 1.93 Å. There are two inequivalent F1- sites. In the first F1- site, F1- is bonded in a single-bond geometry to one Ta3+ atom. In the second F1- site, F1- is bonded in a single-bond geometry to one Ta3+ atom.
