The systematic engineering of molecular complexes with atom-economical efficiency is an exciting area of world-wide research activity as realization of this goal may afford a diverse array of materials suitable for molecule-based electronic applications. These materials continue to be experience world-wide interest owing to their potential use in a variety of high-denisty information storage, sensor, display, and device switching applications. Among the more celebrated switchable molecule-based materials are those derived from cyanometalate anions.Using a building-block approach, molecular precursors are allowed to self-assemble towards a common structural archetype via the formation of M(�-CN)M� pairs. Using a variety of multidentate capping ligands, the directionality and numbers of coordination sites available for M(�-CN)M� unit formation can be controlled at the single-ion level. This strategy allows for the deliberate and systematic preparation of structurally related polynuclear materials with tailored magnetic and optical properties. Recent efforts to understand optical and magnetic bistability in single-molecule magnets and photoresponsive complexes are described.
