Materials Data on AlH12(NO5)3 by Materials Project
AlH12(NO5)3 crystallizes in the monoclinic C2/c space group. The structure is two-dimensional and consists of two AlH12(NO5)3 sheets oriented in the (0, 1, 0) direction. Al3+ is bonded in an octahedral geometry to six O2- atoms. There is two shorter (1.89 Å) and four longer (1.90 Å) Al–O bond length. There are two inequivalent N5+ sites. In the first N5+ site, N5+ is bonded in a trigonal planar geometry to three O2- atoms. All N–O bond lengths are 1.27 Å. In the second N5+ site, N5+ is bonded in a trigonal planar geometry to three O2- atoms. There is two shorter (1.26 Å) and one longer (1.29 Å) N–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 distorted single-bond geometry to two O2- atoms. There is one shorter (1.00 Å) and one longer (1.69 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 1.00 Å. In the fourth 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 fifth H1+ site, H1+ is bonded in a distorted linear geometry to two O2- atoms. There is one shorter (1.01 Å) and one longer (1.59 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 (1.69 Å) H–O bond length. There are eight inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted trigonal planar geometry to one Al3+ and two H1+ atoms. In the second O2- site, O2- is bonded in a distorted trigonal planar geometry to one Al3+ and two H1+ atoms. In the third O2- site, O2- is bonded in a bent 120 degrees geometry to one N5+ and one H1+ atom. In the fourth O2- site, O2- is bonded in a distorted trigonal planar geometry to one Al3+ and two H1+ atoms. In the fifth O2- site, O2- is bonded in a single-bond geometry to one N5+ atom. In the sixth O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one N5+ and one H1+ atom. In the seventh O2- site, O2- is bonded in a bent 120 degrees geometry to one N5+ and one H1+ atom. In the eighth O2- site, O2- is bonded in a distorted single-bond geometry to one N5+ atom.
