Materials Data on Fe4AgXeF5 by Materials Project
XeFe4AgF5 crystallizes in the tetragonal I4/m space group. The structure is two-dimensional and consists of four xenon molecules and two Fe4AgF5 sheets oriented in the (0, 0, 1) direction. In each Fe4AgF5 sheet, Fe is bonded in a 3-coordinate geometry to three F atoms. There are a spread of Fe–F bond distances ranging from 2.00–2.35 Å. Ag is bonded in a square co-planar geometry to four equivalent F atoms. All Ag–F bond lengths are 2.49 Å. There are two inequivalent F sites. In the first F site, F is bonded in a distorted T-shaped geometry to two equivalent Fe and one Ag atom. In the second F site, F is bonded in a square co-planar geometry to four equivalent Fe atoms.
