文摘

The magnesium imide complexes [(ArNMg·diox)₄·3(diox)] (4) and[(ArNMg·THF)₄·tol] (5) (where Ar = 2,4,6-Cl₃C₆H₂, diox = 1,4-dioxane, and THF = tetrahydrofuran) were prepared by theequimolar reaction of Bu₂Mg with the primary amine in suitablesolvent mixtures. The successful synthesis of the halide-substitutedimides is notable because similar reactions with the less acidicorgano-substituted anilines cease upon monodeprotonation. Both4 and 5 form unusual Mg₄N₄ cubane aggregates in the solid state.Computational studies (HF/6-31G*) indicate that a combination ofsterics and metal solvation determines the aggregation stateadopted.
