Materials Data on Sb2IF15 by Materials Project
Sb2F11IF4 crystallizes in the monoclinic P2_1/c space group. The structure is zero-dimensional and consists of four IF4 clusters and four Sb2F11 clusters. In each IF4 cluster, I5+ is bonded in a 4-coordinate geometry to four F1- atoms. There is two shorter (1.85 Å) and two longer (1.90 Å) I–F bond length. There are four inequivalent F1- sites. In the first F1- site, F1- is bonded in a single-bond geometry to one I5+ atom. In the second F1- site, F1- is bonded in a single-bond geometry to one I5+ atom. In the third F1- site, F1- is bonded in a single-bond geometry to one I5+ atom. In the fourth F1- site, F1- is bonded in a single-bond geometry to one I5+ atom. In each Sb2F11 cluster, there are two inequivalent Sb5+ sites. In the first Sb5+ site, Sb5+ is bonded to six F1- atoms to form corner-sharing SbF6 octahedra. The corner-sharing octahedral tilt angles are 26°. There are a spread of Sb–F bond distances ranging from 1.88–2.07 Å. In the second Sb5+ site, Sb5+ is bonded to six F1- atoms to form corner-sharing SbF6 octahedra. The corner-sharing octahedral tilt angles are 26°. There are a spread of Sb–F bond distances ranging from 1.88–2.08 Å. There are eleven 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 the fourth F1- site, F1- is bonded in a single-bond geometry to one Sb5+ 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 seventh F1- site, F1- is bonded in a distorted single-bond geometry to one Sb5+ atom. In the eighth F1- site, F1- is bonded in a distorted single-bond geometry to one Sb5+ atom. In the ninth F1- site, F1- is bonded in a single-bond geometry to one Sb5+ atom. In the tenth F1- site, F1- is bonded in a single-bond geometry to one Sb5+ atom. In the eleventh F1- site, F1- is bonded in a bent 150 degrees geometry to two Sb5+ atoms.
