Various graphitic phases of C₃N₄ are examined using the local-density approximation plane-wave-pseudopotential approach. These are three forms of p graphite and the P6m2 graphite structure. Each differs only in planar stacking and character of planar C-N bonds. Two forms of p graphite are predicted to be stable with energies very close to the P6m2 structure. This suggests a strong phase instability of the graphite structures and material softening along the c axis.
