N-(Pyrazin-2-yl)-1,8-naphthyridin-2-amine

Abstract: There are two independent molecules 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 molecule, an intramolecular C-HN hydrogen bond stabilizes the molecular structure, forming an S(6) ring motif. The independent molecules are linked via an N-HN hydrogen bond. Further N-HN and C-HN hydrogen bonds connect the molecules into chains along c axis. Pairs of C-H [pi] interactions between the chains lead to sheets parallel to the b axis. These are linked by [pi] - [pi] interactions between the naphthyridine and pyrazine rings [centroid-centroid separations of 3.553 (8) Å] into a three-dimensional supramolecular network.
