Materials Data on CaAs2(XeF5)4 by Materials Project
CaAs2(XeF5)4 crystallizes in the monoclinic P2_1 space group. The structure is two-dimensional and consists of one CaAs2(XeF5)4 sheet oriented in the (0, 0, 1) 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 (2.05 Å) and one longer (2.11 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 (2.11 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 (2.07 Å) and one longer (2.09 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 (2.07 Å) and one longer (2.10 Å) Xe–F bond lengths. Ca is bonded in a 8-coordinate geometry to eight F atoms. There are a spread of Ca–F bond distances ranging from 2.34–2.46 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 1.76–1.83 Å.
