Abstract

This review is intended to be a chemist-friendly introduction to what quasicrystals (QCs) and approximant crystals (ACs) are and what chemists may be able to contribute to the field. Readers will first be exposed to a must-know history of QC/ACs, then warmed up with the somewhat distant and prior concepts of metal clusters in halides, oxides etc., and then to polyanionic clusters in Zintl phases and intermetallic systems. Information on these last two has originated over about the last 50 years. We will draw on some more chemical insights and information on how these might be related and applicable to new and expanded QC and AC systems. Then follow our experiences on electronic and chemical tuning of five QC and AC systems and the structural regularities within ACs, from which important clues for quasicrystal structure modeling are evident.
