C3H12NB is Silicon tetrafluoride-derived structured and crystallizes in the trigonal R3m space group. The structure is zero-dimensional and consists of three C3H12NB clusters. B(1) is bonded to one N(1) and three equivalent H(3) atoms to form BH3N tetrahedra that share corners with three equivalent C(1)H3N tetrahedra. C(1) is bonded to one N(1), one H(1), and two equivalent H(2) atoms to form CH3N tetrahedra that share  a cornercorner with one B(1)H3N tetrahedra and corners with two equivalent C(1)H3N tetrahedra. N(1) is bonded in a tetrahedral geometry to one B(1) and three equivalent C(1) atoms. There are three inequivalent H sites. In the first H site, H(1) is bonded in a single-bond geometry to one C(1) atom. In the second H site, H(2) is bonded in a single-bond geometry to one C(1) atom. In the third H site, H(3) is bonded in a single-bond geometry to one B(1) atom.
