Materials Data on SbH3NF6 by Materials Project
NH3SbF6 crystallizes in the monoclinic C2/c space group. The structure is zero-dimensional and consists of eight ammonia molecules and eight SbF6 clusters. In four of the SbF6 clusters, Sb5+ is bonded in an octahedral geometry to six F1- atoms. There is two shorter (1.91 Å) and four longer (1.93 Å) Sb–F bond length. There are three inequivalent F1- sites. In the first F1- site, F1- is bonded in a single-bond geometry to one Sb5+ atom. In the second F1- site, F1- is bonded in a single-bond geometry to one Sb5+ atom. In the third F1- site, F1- is bonded in a single-bond geometry to one Sb5+ atom. In four of the SbF6 clusters, Sb5+ is bonded in an octahedral geometry to six F1- atoms. All Sb–F bond lengths are 1.92 Å. There are three inequivalent F1- sites. In the first F1- site, F1- is bonded in a single-bond geometry to one Sb5+ atom. In the second F1- site, F1- is bonded in a single-bond geometry to one Sb5+ atom. In the third F1- site, F1- is bonded in a single-bond geometry to one Sb5+ atom.
