High Quality Content by WIKIPEDIA articles! Diphosphorus, P2, is the diatomic form of phosphorus. Unlike its nitrogen group neighbour 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 half that of dinitrogen. Traditionally diphosphorus can be generated by heating white phosphorus at 1100 kelvins. Nevertheless, some advancements were obtained in generating the diatomic molecule in homogenous solution, under normal conditions with the use by some transition metal complexes.
