Materials Data on SbI5F6 by Materials Project
SbF6(Sb(IF3)2)2(I)11 crystallizes in the triclinic P-1 space group. The structure is zero-dimensional and consists of eleven hydriodic acid molecules, two Sb(IF3)2 clusters, and one SbF6 cluster. In each Sb(IF3)2 cluster, Sb5+ is bonded in an octahedral geometry to six F1- atoms. There are a spread of Sb–F bond distances ranging from 1.91–1.95 Å. There are two inequivalent I+0.20+ sites. In the first I+0.20+ site, I+0.20+ is bonded in a single-bond geometry to one F1- atom. The I–F bond length is 2.80 Å. In the second I+0.20+ site, I+0.20+ is bonded in a single-bond geometry to one F1- atom. The I–F bond length is 2.81 Å. There are six 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+ and one I+0.20+ atom. In the fourth F1- site, F1- is bonded in a single-bond geometry to one Sb5+ and one I+0.20+ atom. In the fifth F1- site, F1- is bonded in a single-bond geometry to one Sb5+ atom. In the sixth F1- site, F1- is bonded in a single-bond geometry to one Sb5+ atom. In the SbF6 cluster, Sb5+ is bonded in an octahedral geometry to six F1- atoms. There are a spread of Sb–F bond distances ranging from 1.91–1.94 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.
