P2Cl10

P2Cl10, or diphosphorus decachloride, is a chlorine-rich phosphorus compound with the formula P2Cl10. It is commonly described as a dimeric form associated with phosphorus pentachloride chemistry and represents one of several P2Cln species known in the phosphorus–chlorine system. The compound is moisture sensitive and must be prepared and stored under strictly anhydrous conditions.

Structure and preparation

In many descriptions, P2Cl10 is regarded as a dimer of PCl5. The precise ligand arrangement around the

Reactivity and properties

P2Cl10 is highly reactive toward moisture and rapidly hydrolyzes in the presence of water, yielding phosphorus

Safety and handling

The compound is corrosive and toxic, with significant moisture sensitivity. It is handled under inert atmosphere
