Sulfite Anions as Structure-Directing Templates for the Engineering of Modular Polyoxometalates


  • Dedicated to Professor Michael T. Pope on the occasion of his 80th birthday


Polyoxometalates (POMs) are anionic metal oxides and encompass a diverse family of nanosized compounds with an unmatched range of architectures and physical properties. The use of the pyramidal sulfite anion, with its numerous coordination modes, has introduced structural diversity into the POM-based chemical systems, giving rise to the formation of novel synthons for the construction of unprecedented architectures ranging from low-nuclearity, isolable secondary building units to POM-based molecular nanoparticles, open-framework and 3D coordination materials, and the emergence of novel properties.
