项目标书摘要：Nitrides are an important class of inorganic materials,which exhibit outstanding chemical and physical properties.Recently,application of high-pressure high-temperature(HPHT)synthesis techniques has broken previously established paradigms and considerably enriched nitrogen chemistry.The goal of the project is the HPHT synthesis and systematic study of crystal chemistry and physical properties of binary N-Hal and ternary H-N-Hal(Hal=F,Cl,Br,I)compounds.The synthesis will be realized in laser-heated diamond anvil cells(DACs)from various precursors,and the reaction products will be studied using single-crystal X-ray diffraction and Raman spectroscopy,combined with theoretical calculations for a deeper insight into the nature of the chemical bonding and mechanical and electronic properties.We intend to reveal the relationships between synthetic conditions,chemical bonding,structure,and properties of the novel compounds,which will enable to generalize our own observations and previously available data on high-pressure nitrogen chemistry and formulate crystal-chemical principals governing the formation and behavior of nitrogen and halogen containing compounds at extreme conditions.
