C5H5N5

C5H5N5 is a molecular formula describing any molecule that contains five carbon atoms, five hydrogen atoms, and five nitrogen atoms. It does not specify a single compound; rather, it denotes a family of possible isomers and classes of compounds, especially nitrogen-rich heterocycles and their derivatives. The nominal molecular weight is about 135.13 g/mol.

Because of the high nitrogen content, the structures compatible with C5H5N5 can vary widely. Isomers may include cyclic arrangements where nitrogen atoms are interspersed in a ring or rings, as well as open-chain forms with different connectivity. The stability, sensitivity, and energetic characteristics depend strongly on the specific arrangement of atoms and substituents, so there is no universal set of properties for the formula.

In research contexts, C5H5N5 is of interest mainly as a point of study within high-nitrogen compounds and energetic materials. Compounds with this formula have been investigated for their potential as propellants, gas generators, or other applications that rely on the release of nitrogen upon decomposition. However, many such species are highly reactive or unstable, making synthesis and handling challenging and limiting practical use.
