Abstract

There are two independent mol-ecules in the asymmetric unit of the title compound, C12H9N5, in which the C-N(amine)-C angles differ slightly [129.63 (11) and 132.02 (11)°]. In each independent mol-ecule, an intra-molecular C-H⋯N hydrogen bond stabilizes the mol-ecular structure, forming an S(6) ring motif. The independent mol-ecules are linked via an N-H⋯N hydrogen bond. Further N-H⋯N and C-H⋯N hydrogen bonds connect the mol-ecules into chains along c axis. Pairs of C-H⋯π inter-actions between the chains lead to sheets parallel to the b axis. These are linked by π-π inter-actions between the naphthyridine and pyrazine rings [centroid-centroid separations of 3.553 (8) Å] into a three-dimensional supra-molecular network.
