The first supramolecular assemblies comprised of dimetal units and chiral dicarboxylates

The first molecules containing metal–metal bonded Mo24+ units linked by chiral dicarboxylates have been prepared and characterized by X-ray crystallography and 1H NMR spectroscopy; the compounds [Mo2(DAniF)3]2(dicarboxylate), 1 for l-tartrate and 2 for d-aspartate (DAniF=N,N′-di-p-anisylformamidinate) represent a first step toward the synthesis of more complex polygonal structures assembled from M2 units and chiral linkers.
