Abstract and subjects
In the title compound, C5N6, all the atoms are approximately coplanar. In the crystal, molecules are packed with short contact distances of 2.885 (2) (between the diazo N atom connected to the ring and a cyano N atom on a neighboring molecule) and 3.012 (2) angstrom (between the terminal diazo N atom and an N atom of a neighboring imidazole ring).
