Crystal structure determination of adducts of (−)-sparteine and PhLi, (−)-sparteine and PhOLi and of (−)-sparteine and PhLi/PhOLi reveal a four-membered ring with two lithium centers, each capped by a (−)-sparteine ligand, as central motif of all structure. Quantum-chemical calculations show that the mixed aggregate [PhLi·PhOLi·2(−)-sparteine] is energetically more favorable than the model system {1/2[PhLi·(−)-sparteine]2 + 1/2[PhOLi·(−)-sparteine]2}.
