Materials Data on SnH16Se3N7 by Materials Project
SnSe3(NH2)5(NH3)2 crystallizes in the triclinic P-1 space group. The structure is zero-dimensional and consists of ten ammonia molecules, four ammonia molecules, and one SnSe3 cluster. In the SnSe3 cluster, Sn3+ is bonded to four Se2- atoms to form edge-sharing SnSe4 tetrahedra. There are a spread of Sn–Se bond distances ranging from 2.51–2.63 Å. There are three inequivalent Se2- sites. In the first Se2- site, Se2- is bonded in a distorted single-bond geometry to one Sn3+ atom. In the second Se2- site, Se2- is bonded in an L-shaped geometry to two equivalent Sn3+ atoms. In the third Se2- site, Se2- is bonded in a single-bond geometry to one Sn3+ atom.
