“…The solvatochromism of the absorption spectrum is evident in Table and Figure . The LF bands are ordinarily regarded as little solvent sensitive, as tends to be substantiated by occasional reports on chromium(III) cations, with the exception of fluoride-containing species, where the LF strength of the F - ligand is altered by hydrogen bonding with H 2 O. The available data on negative compounds, such as Cr(CN) 6 3- , , Cr(CN) 5 (NH 3 ) 2- , and trans -Cr(NH 3 ) 2 (NCS) 4 - , do show more significant variations, like those observed here. The increase of the LF transition energy on passing from nonaqueous to aqueous environments, that is, the intensified ligand perturbation on the metal ion, is ascribed to tightening of the second coordination sphere by hydrogen bond formation between CN - and H 2 O.…”
