Pentavalent lanthanide nitride-oxides: NPrO and NPrO^- complexes with N[triple bond, length as m-dash]Pr triple bonds.

ABSTRACT: The neutral molecule NPrO and its anion NPrO^- are produced via co-condensation of laser-ablated praseodymium atoms with nitric oxide in a solid neon matrix. Combined infrared spectroscopy and state-of-the-art quantum chemical calculations confirm that both species are pentavalent praseodymium nitride-oxides with linear structures that contain Pr[triple bond, length as m-dash]N triple bonds and Pr[double bond, length as m-dash]O double bonds. Electronic structure studies show that the neutral NPrO molecule features a 4f⁰ electron configuration and a Pr(v) oxidation state similar to that of the isoelectronic PrO₂ ⁺ ion, while its NPrO^- anion possesses a 4f¹ electron configuration and a Pr(iv) oxidation state.
