Diphosphorus is an inorganic chemical with the chemical formula P2. Unlike its nitrogen group neighbor nitrogen which forms a stable N2 molecule with a nitrogen to nitrogen triple bond phosphorus prefers a tetrahedral form P4 because P-P pi-bonds are high in energy. Diphosphorus is therefore very reactive with a bond-dissociation energy (117 kcal/mol or 490 kJ/mol) half that of dinitrogen.
