Metal-dependent alternative activation of O-H and C-H bonds of methanol: on the formation and structure of bare [M,C,H-3,O](+) complexes (M = Fe, Co, Ni) in the gas phase

Structural aspects of the 'bare' [M(C,H-3,O)](+) complexes (M = Fe, Co, Ni), generated by electrospray ionization of aqueous methanolic solutions of MX2 (X = Br, I), have been probed in the gas phase by a combination of labeling studies and collision-induced dissociation (CID) experiments.
