Materials Data on As2Cl3OF5 by Materials Project

As2OCl3F5 is High Pressure (4-7GPa) Tellurium-like structured and crystallizes in the monoclinic P2_1/c space group. The structure is zero-dimensional and consists of four As2OCl3F5 clusters. there are two inequivalent As5+ sites. In the first As5+ site, As5+ is bonded to one O2- and five F1- atoms to form corner-sharing AsOF5 octahedra. The As–O bond length is 1.93 Å. There are a spread of As–F bond distances ranging from 1.76–1.78 Å. In the second As5+ site, As5+ is bonded to one O2- and three Cl1- atoms to form corner-sharing AsCl3O tetrahedra. The corner-sharing octahedral tilt angles are 53°. The As–O bond length is 1.70 Å. There are one shorter (2.10 Å) and two longer (2.11 Å) As–Cl bond lengths. O2- is bonded in a distorted bent 120 degrees geometry to two As5+ atoms. There are three inequivalent Cl1- sites. In the first Cl1- site, Cl1- is bonded in a distorted single-bond geometry to one As5+ atom. In the second Cl1- site, Cl1- is bonded in a distorted single-bond geometry to one As5+ atom. In the third Cl1- site, Cl1- is bonded in a distorted single-bond geometry to one As5+ atom. There are five inequivalent F1- sites. In the first F1- site, F1- is bonded in a single-bond geometry to one As5+ atom. In the second F1- site, F1- is bonded in a single-bond geometry to one As5+ atom. In the third F1- site, F1- is bonded in a single-bond geometry to one As5+ atom. In the fourth F1- site, F1- is bonded in a single-bond geometry to one As5+ atom. In the fifth F1- site, F1- is bonded in a single-bond geometry to one As5+ atom.

Materials Data on AsClOF8 by Materials Project

AsF6OClF2 crystallizes in the orthorhombic Pna2_1 space group. The structure is zero-dimensional and consists of four AsF6 clusters and four OClF2 clusters. In each AsF6 cluster, As is bonded in an octahedral geometry to six F atoms. There are a spread of As–F bond distances ranging from 1.75–1.81 Å. There are six 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 single-bond geometry to one As atom. In the third F site, F is bonded in a single-bond geometry to one As atom. In the fourth F site, F is bonded in a single-bond geometry to one As 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 each OClF2 cluster, O is bonded in a single-bond geometry to one Cl atom. The O–Cl bond length is 1.39 Å. Cl is bonded in a trigonal non-coplanar geometry to one O and two F atoms. Both Cl–F bond lengths are 1.63 Å. There are two inequivalent F sites. In the first F site, F is bonded in a single-bond geometry to one Cl atom. In the second F site, F is bonded in a single-bond geometry to one Cl atom.
