Materials Data on AlH18CS2N3O14 by Materials Project
CN3H6AlH12(SO7)2 crystallizes in the trigonal P31m space group. The structure is two-dimensional and consists of three guanidinium molecules and one AlH12(SO7)2 sheet oriented in the (0, 0, 1) direction. In the AlH12(SO7)2 sheet, there are two inequivalent Al3+ sites. In the first Al3+ site, Al3+ is bonded in an octahedral geometry to six O2- atoms. There is three shorter (1.90 Å) and three longer (1.92 Å) Al–O bond length. In the second Al3+ site, Al3+ is bonded in an octahedral geometry to six O2- atoms. There is three shorter (1.89 Å) and three longer (1.91 Å) Al–O bond length. There are six 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 0.99 Å. In the second H1+ site, H1+ is bonded in a linear geometry to two O2- atoms. There is one shorter (1.01 Å) and one longer (1.57 Å) H–O bond length. In the third H1+ site, H1+ is bonded in a distorted linear geometry to two O2- atoms. There is one shorter (1.01 Å) and one longer (1.60 Å) H–O bond length. In the fourth 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 (1.68 Å) H–O bond length. In the fifth H1+ site, H1+ is bonded in a distorted linear 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 linear geometry to two O2- atoms. There is one shorter (1.00 Å) and one longer (1.64 Å) H–O bond length. There are two inequivalent S2- sites. In the first S2- site, S2- is bonded in a tetrahedral geometry to four O2- atoms. There are a spread of S–O bond distances ranging from 1.48–1.51 Å. In the second S2- site, S2- is bonded in a tetrahedral geometry to four O2- atoms. There is one shorter (1.48 Å) and three longer (1.50 Å) S–O bond length. There are ten inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted trigonal planar geometry to one Al3+ and two equivalent H1+ atoms. In the second O2- site, O2- is bonded in a trigonal planar geometry to one Al3+ and two equivalent H1+ atoms. In the third O2- site, O2- is bonded in a distorted trigonal planar geometry to one Al3+ and two H1+ atoms. In the fourth O2- site, O2- is bonded in a trigonal planar geometry to two equivalent H1+ and one S2- atom. In the fifth O2- site, O2- is bonded in a distorted trigonal planar geometry to two equivalent 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 single-bond geometry to one S2- atom. In the eighth O2- site, O2- is bonded in a single-bond geometry to one S2- atom. In the ninth O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one H1+ and one S2- atom. In the tenth O2- site, O2- is bonded in a trigonal planar geometry to two H1+ and one S2- atom.
