摘要：

The asymmetric unit of the title compound, C4H5N7, comprises two independent but virtually superimposable molecules. Each molecule is planar with the dihedral angles between the five-membered rings being 2.8 (3) and 2.1 (3)degrees. The crystal structure is formed by an extensive network of relatively strong N-H center dot center dot center dot N hydrogen-bond interactions. Individual molecules are arranged into supramolecular zigzag chains running parallel to [001] by way of the strongest NH center dot center dot center dot N interactions. Adjacent chains are interconnected by rather long (D center dot center dot center dot A distances range from ca 3.00 to 3.03 angstrom) but highly directional (interaction angles above ca 173 degrees) hydrogen bonds forming a supramolecular layer in the bc plane.
