coordination mode is best described as a [3 + 3] binding mode,
in agreement with theoretical observations displaying a C3v-
symmetric geometry as the only minimum on the very flat PES.
Thermodynamic data indicate an exergonic formation of the
[E(CN)4]− and [E(CN)5]2− ions but slightly endergonic
reactions for the formation of [E(CN)6]3−. It is obvious that
in the condensed phase solid state/solvent effects such as
electrostatic interaction between cations and anions or ions and
solvent molecules stabilize salts containing such doubly/triply
negatively charged ions with highly dynamic cyanide ligands.
