C3N4 crystallizes in the hexagonal P6_3/m space group. C(1) is bonded to one N(2) and three equivalent N(1) atoms to form corner-sharing CN4 tetrahedra. There are two inequivalent N sites. In the first N site, N(2) is bonded in a trigonal planar geometry to three equivalent C(1) atoms. In the second N site, N(1) is bonded in a trigonal planar geometry to three equivalent C(1) atoms.
C3N4 crystallizes in the hexagonal P6_3/m space group. C(1) is bonded to one N(2) and three equivalent N(1) atoms to form corner-sharing CN4 tetrahedra. The C(1)-N(2) bond length is 1.47 Å. All C(1)-N(1) bond lengths are 1.46 Å. There are two inequivalent N sites. In the first N site, N(2) is bonded in a trigonal planar geometry to three equivalent C(1) atoms. In the second N site, N(1) is bonded in a trigonal planar geometry to three equivalent C(1) atoms.
