C2AsH5(OF3)2 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 C2AsH5(OF3)2 clusters. there are two inequivalent C4+ sites. In the first C4+ site, C4+ is bonded in a tetrahedral geometry to three H1+ and one O2- atom. All C–H bond lengths are 1.09 Å. The C–O bond length is 1.48 Å. In the second C4+ site, C4+ is bonded in a trigonal planar geometry to one H1+ and two O2- atoms. The C–H bond length is 1.09 Å. Both C–O bond lengths are 1.28 Å. As3- is bonded in an octahedral geometry to six F1- atoms. There are a spread of As–F bond distances ranging from 1.76–1.83 Å. There are five inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a single-bond geometry to one C4+ atom. In the second H1+ site, H1+ is bonded in a single-bond geometry to one C4+ atom. In the third H1+ site, H1+ is bonded in a linear geometry to one O2- and one F1- atom. The H–O bond length is 1.02 Å. The H–F bond length is 1.51 Å. In the fourth H1+ site, H1+ is bonded in a single-bond geometry to one C4+ atom. In the fifth H1+ site, H1+ is bonded in a single-bond geometry to one C4+ atom. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a bent 120 degrees geometry to one C4+ and one H1+ atom. In the second O2- site, O2- is bonded in a bent 120 degrees geometry to two C4+ atoms. There are six inequivalent F1- sites. In the first F1- site, F1- is bonded in a single-bond geometry to one As3- atom. In the second F1- site, F1- is bonded in a single-bond geometry to one As3- atom. In the third F1- site, F1- is bonded in a single-bond geometry to one As3- atom. In the fourth F1- site, F1- is bonded in a bent 120 degrees geometry to one As3- and one H1+ atom. In the fifth F1- site, F1- is bonded in a single-bond geometry to one As3- atom. In the sixth F1- site, F1- is bonded in a single-bond geometry to one As3- atom.
