Abstract:

Potassium pentacyanohydrazineruthenate(II) trihydrate has been synthesized and characterized by chemical methods, IR and electronic spectroscopy. The specific rate constants for the formation, kL, and dissociation, k-L, reactions of the [Ru(CN)5L]n- ions (L = N2H4, N2H5 +) were obtained, as well as the corresponding stability constants, KL. A value of pKa for the bonded N2H5 + species was also calculated. The results were interpreted in terms of dissociative-type mechanisms for both reactions, and comparisons were made with the related [Fe(CN)5L]n- system. © 1992.
