The compound described by B3NH7 is Indium-like structured and crystallizes in the monoclinic P2_1/c space group. The structure is zero-dimensional and consists of four B3NH7 clusters. There are three inequivalent B sites. In the first B site, B(1) is bonded to one N(1), one H(1), one H(2), and one H(3) atom to form distorted BH3N tetrahedra that share  a cornercorner with one B(2)H4 tetrahedra and  an edgeedge with one B(3)H3N tetrahedra. In the second B site, B(2) is bonded to one H(3), one H(4), one H(5), and one H(6) atom to form corner-sharing BH4 tetrahedra. In the third B site, B(3) is bonded to one N(1), one H(1), one H(6), and one H(7) atom to form distorted BH3N tetrahedra that share  a cornercorner with one B(2)H4 tetrahedra and  an edgeedge with one B(1)H3N tetrahedra. N(1) is bonded in a 2-coordinate geometry to one B(1) and one B(3) atom. There are seven inequivalent H sites. In the first H site, H(6) is bonded in a water-like geometry to one B(2) and one B(3) atom. In the second H site, H(7) is bonded in a single-bond geometry to one B(3) atom. In the third H site, H(1) is bonded in a distorted L-shaped geometry to one B(1) and one B(3) atom. In the fourth H site, H(2) is bonded in a single-bond geometry to one B(1) atom. In the fifth H site, H(3) is bonded in a water-like geometry to one B(1) and one B(2) atom. In the sixth H site, H(4) is bonded in a single-bond geometry to one B(2) atom. In the seventh H site, H(5) is bonded in a single-bond geometry to one B(2) atom. is represented by the Crystallographic Information File (CIF) [CIF]
