The 1H and 13C NMR spectra of 2 together with an X‐ray crystallographic analysis indicated a C 2v symmetrical structure. DFT calculations on 2 revealed that its LUMO consists of overlapping 3 p‐ and 4 d‐orbitals of the Al and Y atoms, respectively, and that the HOMO–LUMO gap is narrow. The UV/Vis spectrum of 2 exhibited a visible absorption at 432 nm, which suggests that the strong σ‐donating and π‐accepting character of the three‐coordinate dialkylalumanyl ligand generates a colored d^0‐complex that does not contain any π‐electrons., ファイル公開:2021-04-06}, pages = {4520--4523}, title = {An Alumanylyttrium Complex with an Absorption due to a Transition from the Al−Y Bond to an Unoccupied d‐Orbital}, volume = {26}, year = {2020} }
