description: AlB3NH13AlB3NH15 crystallizes in the monoclinic P2_1/c space group. The structure is zero-dimensional and consists of four AlB3NH13 clusters and four AlB3NH15 clusters. In each AlB3NH13 cluster, Al3+ is bonded to one N2- and six H+0.57+ atoms to form distorted AlH6N pentagonal bipyramids that share edges with three BH4 tetrahedra. The Al–N bond length is 1.95 Å. There are a spread of Al–H bond distances ranging from 1.80–1.88 Å. There are three inequivalent B3- sites. In the first B3- site, B3- is bonded to four H+0.57+ atoms to form BH4 tetrahedra that share an edgeedge with one AlH6N pentagonal bipyramid. There are a spread of B–H bond distances ranging from 1.20–1.26 Å. In the second B3- site, B3- is bonded to four H+0.57+ atoms to form BH4 tetrahedra that share an edgeedge with one AlH6N pentagonal bipyramid. There are a spread of B–H bond distances ranging from 1.20–1.25 Å. In the third B3- site, B3- is bonded to four H+0.57+ atoms to form BH4 tetrahedra that share an edgeedge with one AlH6N pentagonal bipyramid.
