Research: When a correlation between the chemical structure and a physical property of a material is postulated, measurements on compounds exhibiting a range of structural variations are required to establish its validity and, ultimately, to optimize performance for an application. Yet the controlled modification of inorganic structures remains, in many instances, an open challenge. Our research is directed toward developing general strategies for the synthesis of inorganic clusters and solids.
