Materials Data on C2N3 by Materials Project
N(CN)2 crystallizes in the orthorhombic Cmc2_1 space group. The structure is three-dimensional. C4+ is bonded to four N+2.67- atoms to form corner-sharing CN4 tetrahedra. There are a spread of C–N bond distances ranging from 1.45–1.48 Å. There are two inequivalent N+2.67- sites. In the first N+2.67- site, N+2.67- is bonded in a trigonal planar geometry to three equivalent C4+ atoms. In the second N+2.67- site, N+2.67- is bonded in a bent 120 degrees geometry to two equivalent C4+ atoms.
