Materials Data on SbNF4 by Materials Project
N2SbF3SbF5 crystallizes in the monoclinic P2_1/c space group. The structure is zero-dimensional and consists of eight ammonia molecules, four antimony trifluoride molecules, and four SbF5 clusters. In each SbF5 cluster, Sb3+ is bonded in a trigonal bipyramidal geometry to five F1- atoms. There is four shorter (1.89 Å) and one longer (1.90 Å) Sb–F bond length. There are five inequivalent F1- sites. In the first F1- site, F1- is bonded in a single-bond geometry to one Sb3+ atom. In the second F1- site, F1- is bonded in a single-bond geometry to one Sb3+ atom. In the third F1- site, F1- is bonded in a single-bond geometry to one Sb3+ atom. In the fourth F1- site, F1- is bonded in a single-bond geometry to one Sb3+ atom. In the fifth F1- site, F1- is bonded in a single-bond geometry to one Sb3+ atom.
