The crystal structure of minerals can be described as a juxtaposition of chemically bonded coordination polyhedra. This structural principle, known since the dawn of structural science, has been extended and generalized to include anion-centred polyhedra and larger building blocks, including rods and layers. The structure-building principles allow fine tuning of both structure and chemical composition and represents one of the most outstanding mechanisms by which Nature produces a wide range of minerals from a relatively limited number of building blocks. The understanding of the features and complexity of these minerals represents a challenge both for the experimental mineralogist and for the theoretician and opens a huge horizon for crystal engineering. The purpose of this session is to provide a forum for theoreticians and experimentalists, where the current state of knowledge of structure-building principles is reviewed and the challenges for future research are put forward.
