Abstract

XeF2Hg(XeF2)4(PF6)2 crystallizes in the orthorhombic Pccn space group. The structure is zero-dimensional and consists of four Hg(XeF2)4 clusters, eight PF6 clusters, and four XeF2 clusters. In each Hg(XeF2)4 cluster, there are two 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 (2.13 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 (2.04 Å) and one longer (2.15 Å) Xe–F bond lengths. Hg is bonded in a 4-coordinate geometry to four F atoms. There are two shorter (2.30 Å) and two longer (2.36 Å) Hg–F bond lengths. There are four inequivalent F sites. In the first F site, F is bonded in a single-bond geometry to one Xe atom. In the second F site, F is bonded in a distorted bent 120 degrees geometry to one Xe and one Hg 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 Hg atom. In each PF6 cluster, P is bonded in an octahedral geometry to six F atoms. There are a spread of P–F bond distances ranging from 1.63–1.67 Å. There are six inequivalent F sites. In the first F site, F is bonded in a single-bond geometry to one P atom. In the second F site, F is bonded in a single-bond geometry to one P atom. In the third F site, F is bonded in a single-bond geometry to one P atom. In the fourth F site, F is bonded in a single-bond geometry to one P atom. In the fifth F site, F is bonded in a single-bond geometry to one P atom. In the sixth F site, F is bonded in a single-bond geometry to one P atom. In each XeF2 cluster, Xe is bonded in a linear geometry to two equivalent F atoms. Both Xe–F bond lengths are 2.08 Å. F is bonded in a single-bond geometry to one Xe atom.
