The cover picture shows the different building blocks of soluble [{(MeLi) 4 (dem) 1.5 } ∞ ]: (MeLi) 4 tetrahedra connected through face to vertex‐bridging methanide groups form rods pointing alternatively up and down (turquoise cylinders). They are connected by diethoxymethane donor molecules (yellow cylinders) to give wide hexagonal channels filled with solvent. While the tetrameric aggregation and the long‐range Li 3 CH 3 ⋅⋅⋅Li interaction from parent [{(MeLi) 4 } ∞ ] is maintained in this solvate, monomeric MeLi is co‐coordinated in [(THF) 3 Li 3 Me{(N t Bu) 3 S}]. The different approaches to tune the aggregation of insoluble [{(MeLi) 4 } ∞ ] are described by D. Stalke et al. on p. 1417 ff.
