The crystal structure described by C3N crystallizes in the orthorhombic P2_12_12_1 space group. There are three inequivalent C sites. In the first C site, C(1) is bonded in a trigonal planar geometry to one C(3) and two equivalent C(2) atoms. In the second C site, C(3) is bonded in a distorted single-bond geometry to one C(1) and one N(1) atom. In the third C site, C(2) is bonded in a distorted trigonal planar geometry to two equivalent C(1) and one N(1) atom. N(1) is bonded in a bent 150 degrees geometry to one C(2) and one C(3) atom. is represented by the CIF card [CIF]
