Abstract:	Attempted crystallization of the bis(aryl)lithium cuprate, Cu₂Li₂(C₆H₄CH₂-NMe₂-2)₄, from diethyl ether/pentane afforded in according to an X-ray diffraction analysis appeared to be the lithium enolate, Li₄OC(=CH₂)C₆H₄CH₂NMe₂-2]₄. This consists of a central Li₄O₄ cube with intramolecular LiN coordination of the CH₂NMe₂ substituent. This enolate, which has also been prepared via an independent route, is the first example of a structurally characterized lithium enolate and contains Li centres that are intramolecularly coordinated.
