Intermolecular Hydrogen Bonding between Neutral Transition Metal Hydrides (η 5 -C 5 H 5 )M(CO) 3 H (M = Mo, W) and Bases

Résumé

The interaction of CpM(CO)3H (M = Mo, W) hydrides as proton donors with different bases (B = pyridine, (n-Oc)3PO, ((CH3)2N)3PO, H3BNEt3) was studied by variable temperature IR spectroscopy and theoretically by DFT/B3LYP calculations. The data obtained show for the first time the formation of intermolecular hydrogen bonds between the neutral transition metal hydrides and bases in solutions of low polarity. These M−H···B hydrogen bonds are shown to precede the hydrides' deprotonation.
