Related but different: The thermal activation of methane by cationic nickel complexes depends crucially on the nature of ligands and the formal oxidation state of the metal, as is illustrated by the isomeric water complexes: whereas [Ni(H2O)]+ is unreactive, the NiIII isomer [Ni(H)(OH)]+ activates the C[BOND]H bond in methane.
