Base free : An alumole was synthesized and treatment with lithium afforded the lithium salt of the alumole dianion. The structures of these two molecules were then investigated. The CC bond lengths of the AlC 4 ring in the dianion are nearly equal. DFT calculations revealed that the 3p(Al)–π* conjugation lowers the LUMO level of the alumole and that coordination of two lithium cations to the alumole dianion results in a planar AlC 4 ring.
