Background

Polyoxometalates (or polyoxoanions) are inorganic nanoclusters or molecular metal-oxide fragments’. Some polyanion derivatives have the potential to become crucial building blocks of solid-state electronic, magnetic and optical devices in modern technology. Recent progress in polyoxometalate chemistry has allowed to design polyoxomolybdates and also polyoxotungstates with multiple functionalities and dimensions in the nano-regime via a bottom-up approach. Therefore this class of molecular compounds is predicted to play an important role in the rapidly expanding field of nanoscience and nanotechnology.The chemistry of nanomolecular polyoxoanions allows for molecular design of materials with interesting electronic and magnetic properties. Furthermore these species frequently exhibit unusual aspects of electron- and energy-transport. Recently, polyoxometalates have also been studied in colloid chemistry and in this context their stabilizing as well as catalytic role has been well established. New materials based on polyoxometalates and related colloidal particles are at a promising stage that can lead to the emergence of new technologies. Polynuclear complexes of paramagnetic metals, or "spin clusters", are an important class of inorganic compounds,particularly those that function as "Molecular nanomagnets".
