Phosphoryl nitride
Phosphoryl nitride in chemistry is a reactive intermediate with the structure OPN. It is a linear oxygen phosphorus nitrogen molecule with a formal double bond between P and O and a triple bond between P and N. It can be obtained in argon matrix isolation at 16 K by laser photolysis of phosphoryl triazide, OP3. OPN and its isomer ONP can interconvert by photoisomerization. Both are valence isoelectronic to [Nitrous oxide|].
Bulk phosphoryl nitride has many polymorphs, similar to its isoelectronic counterpart, silicon dioxide.
