For the first time, unsubstituted mixed lithium and calcium phenolates could be structurally characterized in the solid state. Compound [CaLi 6 (μ 3 ‐OPh) 8 (thf) 6 ] ( 1 ), was obtained from the reaction of CaI 2 with LiOPh in THF, and features two heterocubane units fused via the calcium ion. Upon recrystallization from the bidentate ligand DME, the aggregate [Ca 2 (dme) 2 (μ‐OPh) 6 {Li(dme)} 2 ] ( 2 ) is obtained, in which the metal ions form a chain motif, being pairwise bridged by phenolate. The transformation of 1 into 2 upon addition of DME can be followed by 7 Li‐NMR spectroscopy.
