The first structurally characterized sodium lithate 1 was obtained by selective transmetalation of [Li{(2‐NC 5 H 4 ) 2 CH}(thf) 2 ] ( 2 ) with the superbase 2 /NaO t Bu. The exchange of only half an equivalent of Li ions in 2 is ascribed to the shape and the basicity of the bis(pyridyl)methyl ligand.
