Seventeen aryllithium complexes were studied by 7 Li solid‐state NMR spectroscopy. The solid structures of most of the complexes studied are known from x‐ray crystallography and include differently substituted aryllithium complexes in addition to some phenyllithium complexes. It is shown that the quadrupolar coupling constant, χ, is very sensitive to changes in aggregation and solvation. From the magnitude of χ, it is often possible to deduce the aggregation state and also obtain information about the solvation regarding the number and type of donor atoms coordinating the lithium cation.
