Well-Defined Surface-Bonded Ruthenium Complexes with Molecular Nitrogen

Stable up to 523 K, the bis(dinitrogen) ruthenium and carbonyldinitrogen ruthenium complexes are formed by reaction of N2 with a carbonyl ruthenium species fixed on dealuminated Y zeolite [Eq. (a)]. A stable trans-dicarbonyldinitrogen ruthenium complex is also formed in the presence of CO at 300 K.
