摘要：

Li-O interactions dominate the structure of 1, a molecule that contains the M-C and Li-O functionalities suspected to play a role in superbases involving RLi and R'OM (M = Na, K, Rb, Cs). Compound 1 forms a tmeda-coordinated tetramer with a central Li4O4 cube, and its O atoms have tetragonal-pyramidal coordination. This structure offers a possible explanation of the activation of organolithium compounds by alkali metal alkoxides.
