title: Materials Data on CoAs2S4(O2F3)4 by Materials Project

description: CoAs2S4(O2F3)4 crystallizes in the monoclinic P2_1/c space group. The structure is zero-dimensional and consists of four CoAs2S4(O2F3)4 clusters. Co2+ is bonded to four O2- and two F1- atoms to form CoO4F2 octahedra that share corners with two AsF6 octahedra. The corner-sharing octahedra tilt angles range from 25–31°. There are a spread of Co–O bond distances ranging from 2.06–2.10 Å. There are one shorter (2.04 Å) and one longer (2.06 Å) Co–F bond lengths. There are two inequivalent As5+ sites. In the first As5+ site, As5+ is bonded to six F1- atoms to form AsF6 octahedra that share a cornercorner with one CoO4F2 octahedra. The corner-sharing octahedral tilt angles are 31°. There are a spread of As–F bond distances ranging from 1.75–1.85 Å. In the second As5+ site, As5+ is bonded to six F1- atoms to form AsF6 octahedra that share a cornercorner with one CoO4F2 octahedra. The corner-sharing octahedral tilt angles are 25°. There are a spread of As–F bond distances ranging from 1.76–1.86 Å. There are four inequivalent S4+ sites. In the first S4+ site, S4+ is bonded in a bent 120 degrees geometry to two O2- atoms. There is one shorter (1.44 Å) and one longer (1.46 Å) S–O bond length. In the second S4+ site, S4+ is bonded in a bent 120 degrees geometry to two O2- atoms. There is one shorter (1.44 Å) and one longer (1.46 Å) S–O bond length. In the third S4+ site, S4+ is bonded in a bent 120 degrees geometry to two O2- atoms. There is one shorter (1.44 Å) and one longer (1.47 Å) S–O bond length. In the fourth S4+ site, S4+ is bonded in a bent 120 degrees geometry to two O2- atoms. There is one shorter (1.44 Å) and one longer (1.46 Å) S–O bond length. There are eight inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted linear geometry to one Co2+ and one S4+ atom. In the second O2- site, O2- is bonded in a single-bond geometry to one S4+ atom. In the third O2- site, O2- is bonded in a bent 150 degrees geometry to one Co2+ and one S4+ atom. In the fourth O2- site, O2- is bonded in a single-bond geometry to one S4+ atom. In the fifth O2- site, O2- is bonded in a bent 150 degrees geometry to one Co2+ and one S4+ atom. In the sixth O2- site, O2- is bonded in a single-bond geometry to one S4+ atom. In the seventh O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Co2+ and one S4+ atom. In the eighth O2- site, O2- is bonded in a single-bond geometry to one S4+ atom. There are twelve inequivalent F1- sites. In the first F1- site, F1- is bonded in a bent 150 degrees geometry to one Co2+ and 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. In the sixth F1- site, F1- is bonded in a single-bond geometry to one As5+ atom. In the seventh F1- site, F1- is bonded in a single-bond geometry to one As5+ atom. In the eighth F1- site, F1- is bonded in a bent 150 degrees geometry to one Co2+ and one As5+ atom. In the ninth F1- site, F1- is bonded in a single-bond geometry to one As5+ atom. In the tenth F1- site, F1- is bonded in a single-bond geometry to one As5+ atom. In the eleventh F1- site, F1- is bonded in a single-bond geometry to one As5+ atom. In the twelfth F1- site, F1- is bonded in a single-bond geometry to one As5+ atom.
