AlN2H14O13NO3(H2O)2 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional and consists of four nitric acid molecules, eight water molecules, and one AlN2H14O13 framework. In the AlN2H14O13 framework, there are two inequivalent Al3+ sites. In the first Al3+ site, Al3+ is bonded in an octahedral geometry to six O2- atoms. All Al–O bond lengths are 1.89 Å. In the second Al3+ site, Al3+ is bonded in an octahedral geometry to six O2- atoms. There are a spread of Al–O bond distances ranging from 1.88–1.91 Å. There are two inequivalent N5+ sites. In the first 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. In the second N5+ site, N5+ is bonded in a trigonal planar geometry to three O2- atoms. All N–O bond lengths are 1.27 Å. There are fourteen 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 1.00 Å. In the second 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 third H1+ site, H1+ is bonded in a distorted single-bond geometry to one O2- atom. The H–O bond length is 1.01 Å. 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 (1.67 Å) H–O bond length. In the fifth 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 sixth H1+ site, H1+ is bonded in a distorted 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 two O2- atoms. There is one shorter (1.00 Å) and one longer (1.73 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 (1.71 Å) H–O bond length. In the ninth 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 tenth H1+ site, H1+ is bonded in a distorted single-bond geometry to two O2- atoms. There is one shorter (1.01 Å) and one longer (1.65 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 one O2- atom. The H–O bond length is 1.00 Å. In the thirteenth 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 fourteenth H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.99 Å. There are thirteen inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted single-bond geometry to one N5+ atom. In the second O2- site, O2- is bonded in a water-like geometry to one N5+ and one H1+ atom. In the third O2- site, O2- is bonded in a distorted water-like geometry to one N5+ and one H1+ atom. In the fourth O2- site, O2- is bonded in a distorted water-like geometry to one N5+ and one H1+ atom. In the fifth O2- site, O2- is bonded in a distorted water-like geometry to one N5+ and one H1+ 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 distorted water-like geometry to three H1+ atoms. In the thirteenth O2- site, O2- is bonded in a distorted single-bond geometry to one N5+ atom.
