Unexpected conversion of a hexacyanometallate to a homoleptic nitrile complex with triphenylborane substituents.

The homoleptic, triphenylborane adduct of the hexacyanochromate anion was structurally characterized and found to be a product in which all six cyanide ligands have undergone isomerization to nitrile groups.
