Praseodymium(V) oxide nitride

Chemical compound From Wikipedia, the free encyclopedia

Praseodymium(V) oxide nitride is a compound of praseodymium in the oxidation state of +5 with the chemical formula PrNO. It was first reported in 2000.[1] However, the compound was not 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.[2] Calculation shows a significant level of f-orbital covalence of Pr-X bonds.[3]

Reactions

Praseodymium(V) oxide nitride further reacts with nitric oxide to form complexes such as NPrO(NO) and NPrO(NO)2 which shows that this compound is a lewis acid. This compound also decomposes to praseodymium(IV) oxide and nitrogen:[2]

PrNO → PrO2 + N2
