资源简介：
The reaction of AlMe3 with tBuLi in
the presence of trimethylacetonitrile affords the bimetallic complex
[tBu(Me)Al(μ-Me)2Li·NC(tBu)]∞ (1). Pseudotetrahedral
Al centers form by the nucelophilic addition of tBuLi to AlMe3.The alkali-metal center is stabilized through
coordination of the unreacted nitrile and polymer formation via the
construction of Al(μ-Me)nLi (n = 1, 2) motifs. Neutron diffraction evidences agostic
interactions in the bridging methyl group to give further stabilization.
There is only one previous report of a neutron structure of a lithium
aluminate compound. This work therefore offers an important structural
example of agostic interactions and the precise nature of Al(μ-Me)2Li bridging.
