Photolytic ligand displacement and salt metathesis routes have been exploited to give access to κ(1) σ-alane complexes featuring Al-H bonds bound to [W(CO)(5)] and [Cp'Mn(CO)(2)] fragments, together with a related κ(2) complex of [Cr(CO)(4)]. Spectroscopic, crystallographic, and quantum chemical studies are consistent with the alane ligands acting predominantly as σ-donors, with the resulting binding energies calculated to be marginally greater than those found for related dihydrogen complexes.
光解配体取代和盐交换反应途径已被利用，以获得κ(1)σ-铝烷配合物，其特征是 Al-H 键与[W(CO)(5)]和[Cp'Mn(CO)(2)]片段结合，以及[Cr(CO)(4)]的相关κ(2)配合物。光谱、晶体学和量子化学研究表明，铝烷配体主要作为σ-供体，计算得到的结合能略大于相关的双氢配合物。
