Praseodymium(V) oxide nitride (original) (raw)

Praseodymium(V) oxide nitride is a compound of praseodymium in the oxidation state of +5 with the formula PrNO, which was first reported in 2000, however, the compound wasn't verified to have an oxidation state of +5 until 2017. This compound is produced by the reaction of praseodymium metal and nitric oxide in 4K and solid neon. The crystal structure is linear with the praseodymium forming a triple bond with the nitrogen and a double bond with the oxygen. Calculation shows a significant level of f-orbital covalence of Pr-X bonds.
