Description

This research is concerned with the investigation of a largely unexplored family of solid state hydrides which is based on intermetallic compounds that constitute of s- and p-block metals/semimetals (Zintl phases). The peculiar feature of such hydrides is the coexistence of hydrogen and polymeric anions composed of p-block atoms which creates unprecedented coordination environments and bonding situations for the participating atoms. Hydrogenous Zintl phases are important model systems for fundamental studies of hydrogen-metal interactions, while at the same time hydrogen-induced chemical structure and physical property changes provide exciting prospects for materials science. We address the exploration of the compositional range of hydrogenous Zintl phases by different methods of synthesis, their structure and property characterization, as well as their spectroscopic investigation. The fundamental goal is to extract a conclusive picture of hydrogen-main group metal bonding interactions and their consequences to materials properties.
