Materials Data on Sb8Cl2O11 by Materials Project

Sb8O11Cl2 crystallizes in the triclinic P-1 space group. The structure is two-dimensional and consists of one Sb8O11Cl2 sheet oriented in the (0, 0, 1) direction. there are four inequivalent Sb3+ sites. In the first Sb3+ site, Sb3+ is bonded in a distorted square co-planar geometry to four O2- atoms. There are a spread of Sb–O bond distances ranging from 2.00–2.25 Å. In the second Sb3+ site, Sb3+ is bonded in a 2-coordinate geometry to two O2- and one Cl1- atom. There is one shorter (1.98 Å) and one longer (2.00 Å) Sb–O bond length. The Sb–Cl bond length is 2.55 Å. In the third Sb3+ site, Sb3+ is bonded in a distorted T-shaped geometry to three O2- atoms. There are two shorter (2.00 Å) and one longer (2.01 Å) Sb–O bond lengths. In the fourth Sb3+ site, Sb3+ is bonded in a rectangular see-saw-like geometry to four O2- atoms. There are a spread of Sb–O bond distances ranging from 2.01–2.25 Å. There are six inequivalent O2- sites. In the first O2- site, O2- is bonded in a 3-coordinate geometry to three Sb3+ atoms. In the second O2- site, O2- is bonded in a distorted trigonal non-coplanar geometry to three Sb3+ atoms. In the third O2- site, O2- is bonded in a distorted bent 150 degrees geometry to two Sb3+ atoms. In the fourth O2- site, O2- is bonded in a bent 120 degrees geometry to two Sb3+ atoms. In the fifth O2- site, O2- is bonded in a linear geometry to two equivalent Sb3+ atoms. In the sixth O2- site, O2- is bonded in a bent 120 degrees geometry to two Sb3+ atoms. Cl1- is bonded in a single-bond geometry to one Sb3+ atom.
