Materials Data on AsS(IF3)2 by Materials Project
AsS(IF3)2 crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. there are two inequivalent As2- sites. In the first As2- site, As2- is bonded in an octahedral geometry to six F1- atoms. There is two shorter (1.77 Å) and four longer (1.78 Å) As–F bond length. In the second As2- site, As2- is bonded in an octahedral geometry to six F1- atoms. There is four shorter (1.77 Å) and two longer (1.79 Å) As–F bond length. S2- is bonded in a 5-coordinate geometry to one S2-, two I5+, and three F1- atoms. The S–S bond length is 1.86 Å. There are one shorter (2.86 Å) and one longer (3.24 Å) S–I bond lengths. There are a spread of S–F bond distances ranging from 2.98–3.32 Å. There are two inequivalent I5+ sites. In the first I5+ site, I5+ is bonded in a distorted single-bond geometry to one S2-, one I5+, and one F1- atom. The I–I bond length is 2.63 Å. The I–F bond length is 2.89 Å. In the second I5+ site, I5+ is bonded in an L-shaped geometry to one S2- and one I5+ atom. There are six inequivalent F1- sites. In the first F1- site, F1- is bonded in a single-bond geometry to one As2- atom. In the second F1- site, F1- is bonded in a single-bond geometry to one As2- atom. In the third F1- site, F1- is bonded in a single-bond geometry to one As2- and one S2- atom. In the fourth F1- site, F1- is bonded in a single-bond geometry to one As2- and one S2- atom. In the fifth F1- site, F1- is bonded in a single-bond geometry to one As2- and one I5+ atom. In the sixth F1- site, F1- is bonded in a single-bond geometry to one As2- and one S2- atom.
