Materials Data on CdAs2(XeF5)4 by Materials Project

Abstract

CdAs2(XeF5)4 crystallizes in the orthorhombic P2_12_12_1 space group. The structure is one-dimensional and consists of two CdAs2(XeF5)4 ribbons oriented in the (1, 0, 0) direction. there are four inequivalent Xe sites. In the first Xe site, Xe is bonded in a linear geometry to two F atoms. There are one shorter (2.04 Å) and one longer (2.14 Å) Xe–F bond lengths. In the second Xe site, Xe is bonded in a linear geometry to two F atoms. There are one shorter (2.05 Å) and one longer (2.12 Å) Xe–F bond lengths. In the third Xe site, Xe is bonded in a linear geometry to two F atoms. There are one shorter (2.04 Å) and one longer (2.14 Å) Xe–F bond lengths. In the fourth Xe site, Xe is bonded in a linear geometry to two F atoms. There are one shorter (2.08 Å) and one longer (2.10 Å) Xe–F bond lengths. Cd is bonded in a 8-coordinate geometry to eight F atoms. There are a spread of Cd–F bond distances ranging from 2.29–2.50 Å. There are two inequivalent As sites. In the first As site, As is bonded in an octahedral geometry to six F atoms. There are a spread of As–F bond distances ranging from 1.76–1.84 Å. In the second As site, As is bonded in an octahedral geometry to six F atoms. There are a spread of As–F bond distances ranging from 1.75–1.82 Å. There are twenty inequivalent F sites. In the first F site, F is bonded in a single-bond geometry to one As atom. In the second F site, F is bonded in a bent 150 degrees geometry to one Xe and one Cd atom. In the third F site, F is bonded in a single-bond geometry to one Xe atom. In the fourth F site, F is bonded in a bent 150 degrees geometry to one Xe and one Cd atom. In the fifth F site, F is bonded in a single-bond geometry to one As atom. In the sixth F site, F is bonded in a single-bond geometry to one As atom. In the seventh F site, F is bonded in a single-bond geometry to one As atom. In the eighth F site, F is bonded in a single-bond geometry to one As atom. In the ninth F site, F is bonded in a single-bond geometry to one Xe atom. In the tenth F site, F is bonded in a distorted bent 120 degrees geometry to one Xe and one Cd atom. In the eleventh F site, F is bonded in a distorted bent 150 degrees geometry to one Xe and one Cd atom. In the twelfth F site, F is bonded in a water-like geometry to one Cd and one As atom. In the thirteenth F site, F is bonded in a water-like geometry to one Cd and one As atom. In the fourteenth F site, F is bonded in a single-bond geometry to one Xe atom. In the fifteenth F site, F is bonded in a single-bond geometry to one As atom. In the sixteenth F site, F is bonded in a single-bond geometry to one As atom. In the seventeenth F site, F is bonded in a bent 120 degrees geometry to one Xe and one Cd atom. In the eighteenth F site, F is bonded in a distorted bent 150 degrees geometry to one Cd and one As atom. In the nineteenth F site, F is bonded in a single-bond geometry to one As atom. In the twentieth F site, F is bonded in a single-bond geometry to one As atom.
