description: (CH3)3AlH12(SO5)3 crystallizes in the monoclinic P2_1/c space group. The structure is two-dimensional and consists of twelve methane molecules and one AlH12(SO5)3 sheet oriented in the (1, 0, 0) direction. In the AlH12(SO5)3 sheet, Al3+ is bonded in an octahedral geometry to six O2- atoms. There are a spread of Al–O bond distances ranging from 1.88–1.92 Å. There are twelve inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a distorted linear geometry to two O2- atoms. There is one shorter (1.01 Å) and one longer (1.63 Å) H–O bond length. In the second H1+ site, H1+ is bonded in a linear geometry to two O2- atoms. There is one shorter (1.02 Å) and one longer (1.56 Å) H–O bond length. In the third 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 fourth H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.99 Å. In the fifth 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 (1.63 Å) H–O bond length. In the sixth 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 (1.67 Å) H–O bond length. In the seventh H1+ site, H1+ is bonded in a single-bond geometry to two O2- atoms. There is one shorter (1.00 Å) and one longer (1.70 Å) H–O bond length. In the eighth H1+ site, H1+ is bonded in a single-bond geometry to two O2- atoms. There is one shorter (1.00 Å) and one longer (1.73 Å) H–O bond length. In the ninth H1+ site, H1+ is bonded in a linear geometry to two O2- atoms. There is one shorter (1.02 Å) and one longer (1.54 Å) H–O bond length. In the tenth H1+ site, H1+ is bonded in a single-bond geometry to two O2- atoms. There is one shorter (0.99 Å) and one longer (1.72 Å) H–O bond length. In the eleventh 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 twelfth 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. There are three inequivalent S2- sites. In the first S2- site, S2- is bonded in a distorted trigonal non-coplanar geometry to three O2- atoms. There is two shorter (1.47 Å) and one longer (1.50 Å) S–O bond length. In the second S2- site, S2- is bonded in a distorted trigonal non-coplanar geometry to three O2- atoms. There is one shorter (1.46 Å) and two longer (1.49 Å) S–O bond length. In the third S2- site, S2- is bonded in a distorted trigonal non-coplanar geometry to three O2- atoms. All S–O bond lengths are 1.48 Å. There are fifteen inequivalent O2- sites. In the first O2- site, O2- is bonded in a 2-coordinate geometry to one H1+ and one S2- atom. In the second O2- site, O2- is bonded in a distorted single-bond geometry to one S2- atom. In the third O2- site, O2- is bonded in a bent 120 degrees geometry to one H1+ and one S2- atom. In the fourth O2- site, O2- is bonded in a bent 120 degrees geometry to one H1+ and one S2- atom. In the fifth O2- site, O2- is bonded in a bent 120 degrees geometry to one H1+ and one S2- atom. In the sixth O2- site, O2- is bonded in a distorted trigonal planar geometry to one Al3+ and two H1+ atoms. In the seventh O2- site, O2- is bonded in a distorted trigonal planar geometry to one Al3+ and two H1+ atoms. In the eighth O2- site, O2- is bonded in a distorted trigonal planar geometry to one Al3+ and two H1+ atoms. In the ninth O2- site, O2- is bonded in a distorted trigonal planar geometry to one Al3+ and two H1+ atoms. In the tenth O2- site, O2- is bonded in a distorted trigonal planar geometry to one Al3+ and two H1+ atoms. In the eleventh O2- site, O2- is bonded in a distorted trigonal planar geometry to one Al3+ and two H1+ atoms. In the twelfth O2- site, O2- is bonded in a trigonal planar geometry to two H1+ and one S2- atom. In the thirteenth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one H1+ and one S2- atom. In the fourteenth O2- site, O2- is bonded in a distorted single-bond geometry to one H1+ and one S2- atom. In the fifteenth O2- site, O2- is bonded in a distorted single-bond geometry to two H1+ and one S2- atom.
