Popis: | The effects of moving the donor N-atom from the 2-position in lithium (2-pyridyl)- and (2-quinolyl)aluminates to the more remote position in (8-quinolyl)aluminates have been investigated by solid-state structural and DFT computational studies of the new complexes [{EtAl(2-qy)3}Li(μ-X)Li(THF)3] (X = Cl/Br 62 : 38) [(1)Li(μ-X)Li(THF)3], [{(EtAl(2-qy)3)Li}2(μ-Br)]−Li(THF)4+ [{1Li}2(μ-Br)]−Li(THF)4+, [{EtAl(2-Me-8-qy)3}Li] [(2)Li], [{Me2Al(2-Me-8-qy)2}Li(THF)] [(3a)Li(THF)], [{Me2Al(6-Me-2-py)2}Li(THF)2] [(4)Li(THF)2] and [{{EtAl(2-Me-8-qy)2}2O}(Li2THF)] (5). Increasing the remoteness of the donor N-atom from the bridgehead results in large differences in the coordination of the Li+ cations by the (8-quinolyl)aluminate anions compared to 2-quinolyl or 2-pyridyl counterparts. The results are of potential interest in understanding how the coordination sites of ligands of this type can be tuned for the coordination requirements of specific metal centres. |
