Phosphoryl nitride

Phosphoryl nitride in chemistry is a reactive intermediate with the structure OPN.^[1] It is a linear oxygen phosphorus nitrogen molecule with a formal double bond between P and O (phosphoryl) and a triple bond (nitride) between P and N. It can be obtained in argon matrix isolation at 16 K by laser photolysis of phosphoryl triazide, OP(N₃)₃.^[2] OPN and its isomer ONP can interconvert by photoisomerization. Both are valence isoelectronic to N₂O.

Bulk phosphoryl nitride has many polymorphs, similar to its isoelectronic counterpart, silicon dioxide.^[3]
