文摘

Photolytic ligand displacement and salt metathesis routes have been exploited to give access to 魏p>1p> 蟽-alane complexes featuring Al鈥揌 bonds bound to [W(CO)₅] and [Cp鈥睲n(CO)₂] fragments, together with a related 魏p>2p> complex of [Cr(CO)₄]. Spectroscopic, crystallographic, and quantum chemical studies are consistent with the alane ligands acting predominantly as 蟽-donors, with the resulting binding energies calculated to be marginally greater than those found for related dihydrogen complexes.
