Designed synthesis, structure, and properties of a family of ferecrystalline compounds [(PbSe)(1.00)](m)(MoSe2)(n).

The targeted synthesis of multiple compounds with specific controlled nanostructures and identical composition is a grand challenge in materials chemistry. We report the synthesis of the new metastable compounds [(PbSe)1.00]m(MoSe2)n using precursors each designed to self-assemble into a specific compound.
