Materials Data on AlH18(BrO6)3 by Materials Project
(H2)2(AlH8O7Br)2(HO2)4(H2O)4H2O2(HO2Br)2(O2)2(Br)2 crystallizes in the triclinic P-1 space group. The structure is zero-dimensional and consists of two hydrobromic acid molecules, two hydrogen molecules, two hydrogen peroxide molecules, two hydroxyperoxide molecules, two hypobromous acid;hydrate molecules, four water molecules, two water molecules, and two AlH8O7Br clusters. In each AlH8O7Br cluster, Al3+ is bonded in a see-saw-like geometry to four O2- atoms. There are a spread of Al–O bond distances ranging from 1.74–1.99 Å. There are eight inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.98 Å. In the second H1+ site, H1+ is bonded in a distorted single-bond geometry to two O2- atoms. There is one shorter (1.00 Å) and one longer (1.66 Å) H–O bond length. In the third H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.97 Å. In the fourth H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.97 Å. In the fifth H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.97 Å. In the sixth H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 1.00 Å. In the seventh H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.97 Å. In the eighth H1+ site, H1+ is bonded in a linear geometry to two O2- atoms. There is one shorter (1.05 Å) and one longer (1.41 Å) H–O bond length. There are seven inequivalent O2- sites. In the first O2- site, O2- is bonded in a single-bond geometry to one Br5+ atom. The O–Br bond length is 1.81 Å. In the second O2- site, O2- is bonded in a distorted trigonal non-coplanar geometry to one Al3+ and two H1+ atoms. In the third O2- site, O2- is bonded in a single-bond geometry to one Al3+ atom. In the fourth O2- site, O2- is bonded in a distorted trigonal planar geometry to three H1+ atoms. In the fifth O2- site, O2- is bonded in a distorted water-like geometry to three H1+ atoms. In the sixth O2- site, O2- is bonded in a 3-coordinate geometry to one Al3+ and two H1+ atoms. In the seventh O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Al3+ and one Br5+ atom. The O–Br bond length is 2.07 Å. Br5+ is bonded in a distorted linear geometry to two O2- atoms.
