Assignemtn of the metal–dinitrogen stretching frequency in ruthenium and osmium pentammine dinitrogen salts
Abstract
A new assignment is proposed for v(M–N2)(M = Ru or Os) in dinitrogen complexes of type [Ru(NH3)5N2]X2(X = Cl, Br, I, or BF4) based on deuteriation shifts and solid state Raman intensities, while polarised solution Raman data support a previous assignement of the osmium analogues.
