BC2N crystallizes in the monoclinic C2 space group. B(1) is bonded in a 4-coordinate geometry to one B(1), one C(1), one C(2), and one N(1) atom. There are two inequivalent C sites. In the first C site, C(1) is bonded in a 2-coordinate geometry to one B(1), one C(2), and one N(1) atom. In the second C site, C(2) is bonded in a distorted tetrahedral geometry to one B(1), one C(1), one C(2), and one N(1) atom. N(1) is bonded in a trigonal planar geometry to one B(1), one C(1), and one C(2) atom.
