Preparation, characterization and substitution kinetics in the complexes of pentacyanoruthenate(II) with hydrazine
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...
