Hexaphosphabenzene is a hypothetical molecular allotrope of phosphorus and analogue of benzene, with chemical formula P₆. It is expected to share the planar structure of benzene, to which it is valence-isoelectronic, due to resonance stabilization and its sp² nature. The pure substance has not been synthesized, but it has been studied computationally and some complexes have been synthesized.
