Materials Data on SnH18C6Br3N by Materials Project
N(CH3)4SnC2H6Br3 is Silicon tetrafluoride-derived structured and crystallizes in the orthorhombic Pbcm space group. The structure is zero-dimensional and consists of four tetramethylammonium molecules and four SnC2H6Br3 clusters. In each SnC2H6Br3 cluster, Sn4+ is bonded in a trigonal bipyramidal geometry to two C+2.67- and three Br1- atoms. Both Sn–C bond lengths are 2.15 Å. There are one shorter (2.57 Å) and two longer (2.79 Å) Sn–Br bond lengths. There are two inequivalent C+2.67- sites. In the first C+2.67- site, C+2.67- is bonded in a distorted trigonal non-coplanar geometry to one Sn4+ and three H1+ atoms. There is two shorter (1.09 Å) and one longer (1.10 Å) C–H bond length. In the second C+2.67- site, C+2.67- is bonded in a distorted trigonal non-coplanar geometry to one Sn4+ and three H1+ atoms. There is two shorter (1.09 Å) and one longer (1.10 Å) C–H bond length. There are four inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a single-bond geometry to one C+2.67- atom. In the second H1+ site, H1+ is bonded in a single-bond geometry to one C+2.67- atom. In the third H1+ site, H1+ is bonded in a single-bond geometry to one C+2.67- atom. In the fourth H1+ site, H1+ is bonded in a single-bond geometry to one C+2.67- atom. There are two inequivalent Br1- sites. In the first Br1- site, Br1- is bonded in a single-bond geometry to one Sn4+ atom. In the second Br1- site, Br1- is bonded in a single-bond geometry to one Sn4+ atom.
