Pentazine is a hypothetical chemical compound that consists of a six-membered aromatic ring containing five nitrogen atoms with the molecular formula C H N5. The name pentazine is used in the nomenclature of derivatives of this compound.

Pentazine is predicted to be unstable and to decompose into hydrogen cyanide (HCN) and nitrogen (N2). [1] The activation energy required is predicted to be around 20 kJ/mol. [2]
