文摘

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.
