Diphosphorus

Diphosphorus is an inorganic chemical with the chemical formula P
2. 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. The bond distance has been measured at 1.8934 Å.
