title: Materials Data on Sn3H28C9IN by Materials Project

description: Sn3C9NH28I is SC16 CuCl, stable at 5GPa structured and crystallizes in the cubic P2_13 space group. The structure is zero-dimensional and consists of eight hydriodic acid molecules and eight Sn3C9NH28 clusters. In four of the Sn3C9NH28 clusters, Sn4+ is bonded to three C4- and one N3- atom to form corner-sharing SnC3N tetrahedra. There are two shorter (2.15 Å) and one longer (2.16 Å) Sn–C bond lengths. The Sn–N bond length is 2.22 Å. There are three inequivalent C4- sites. In the first C4- site, C4- is bonded in a distorted trigonal non-coplanar geometry to one Sn4+ and three H1+ atoms. All C–H bond lengths are 1.10 Å. In the second C4- site, C4- is bonded in a distorted trigonal non-coplanar geometry to one Sn4+ and three H1+ atoms. All C–H bond lengths are 1.10 Å. In the third C4- site, C4- is bonded in a distorted trigonal non-coplanar geometry to one Sn4+ and three H1+ atoms. All C–H bond lengths are 1.10 Å. N3- is bonded in a distorted single-bond geometry to three equivalent Sn4+ and one H1+ atom. The N–H bond length is 1.03 Å. There are ten 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 single-bond geometry to one C4- atom. 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. In the sixth H1+ site, H1+ is bonded in a single-bond geometry to one C4- atom. In the seventh H1+ site, H1+ is bonded in a single-bond geometry to one C4- atom. In the eighth H1+ site, H1+ is bonded in a single-bond geometry to one N3- atom. In the ninth H1+ site, H1+ is bonded in a single-bond geometry to one C4- atom. In the tenth H1+ site, H1+ is bonded in a single-bond geometry to one C4- atom. In four of the Sn3C9NH28 clusters, Sn4+ is bonded to three C4- and one N3- atom to form corner-sharing SnC3N tetrahedra. There are one shorter (2.14 Å) and two longer (2.15 Å) Sn–C bond lengths. The Sn–N bond length is 2.22 Å. There are three inequivalent C4- sites. In the first C4- site, C4- is bonded in a distorted trigonal non-coplanar geometry to one Sn4+ and three H1+ atoms. There is one shorter (1.09 Å) and two longer (1.10 Å) C–H bond length. In the second C4- site, C4- is bonded in a distorted trigonal non-coplanar geometry to one Sn4+ and three H1+ atoms.

There is one shorter (1.09 Å) and two longer (1.10 Å) C–H bond length. N3- is bonded in a distorted single-bond geometry to three equivalent Sn4+ and one H1+ atom. The N–H bond length is 1.04 Å. There are ten 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.
