Materials Data on AsH10C3I by Materials Project
C3AsH10I crystallizes in the orthorhombic Pnma space group. The structure is zero-dimensional and consists of four hydriodic acid molecules and four C3AsH10 clusters. In each C3AsH10 cluster, there are two inequivalent C2- sites. In the first C2- site, C2- is bonded to one As3- and three H1+ atoms to form distorted corner-sharing CAsH3 tetrahedra. The C–As bond length is 1.92 Å. All C–H bond lengths are 1.10 Å. In the second C2- site, C2- is bonded to one As3- and three H1+ atoms to form distorted corner-sharing CAsH3 tetrahedra. The C–As bond length is 1.93 Å. All C–H bond lengths are 1.10 Å. As3- is bonded in a tetrahedral geometry to three C2- and one H1+ atom. The As–H bond length is 1.51 Å. There are six inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a single-bond geometry to one C2- atom. In the second H1+ site, H1+ is bonded in a single-bond geometry to one As3- atom. In the third H1+ site, H1+ is bonded in a single-bond geometry to one C2- atom. In the fourth H1+ site, H1+ is bonded in a single-bond geometry to one C2- atom. In the fifth H1+ site, H1+ is bonded in a single-bond geometry to one C2- atom. In the sixth H1+ site, H1+ is bonded in a single-bond geometry to one C2- atom.
