    • In addition to the halogen bonds and hydrogen bonds observed here, simple Lewis acids such as alkali metal cations have been shown to interact side-on with coordinated cyanide ligands, i.e, with the C=N bond rather than the nitrogen lone pair, see refs 8a and 8e

    • We note that there is no evidence for an additional [Ru(4,4′- tBu2-bipy)(CN)4]2- → pyridinium charge-transfer band, which might be expected, cf. the titration of hexacyanoferrate(II) with a pyridinium cation which generated a hexacyanoferrate(II) → pyridinium charge-transfer transition at the blue end of the visible region of the spectrum (ref 21, However, this CT transition was weak (ε, 41 M-1 cm-1, and such a transition would be obscured by the MLCT transitions associated with the [Ru(4,4′-tBu2-bipy)(CN)4]2- complex which are two orders of magnitude more intense
