Electronic d-d spectra and ligand-dissociation rates of pentacyanoruthenate(II) ions
The electronic spectra of a series of [Ru(CN)<inf>5</inf>L]n- complexes (L = H<inf>2</inf>O, NH<inf>3</inf>, pyrazine, dimethyl sulphoxide, or CN-) have been measured in aqueous solution. The d-d bands were assigned on the basis of a ligand-field model for tetrago...
