摘要：

Pressure has long served as a clean and efficient tool for altering material properties or creating extreme conditions to synthesize novel materials unattainable under ambient conditions. It opens the door to a new realm, promising an order of magnitude more materials waiting to be discovered than those accessible at standard conditions. This discussion comprises two key topics. Firstly, we delve into the transformative impact of pressure on the crystal structure, atomic vibrations, and electronic configuration of metal iodates—a cutting-edge category of non-linear optical materials. The interplay between crystal structure and various properties will be thoroughly explored. Secondly, we explore the synthesis of nitrogen-rich materials, showcasing their dual characteristics of ultra-incompressibility and hardness, or high energy density. Additionally, we introduce state-of-the-art probing methods employed for characterizing the crystal structure of these synthesized materials, with a focus on single-crystal X-ray diffraction from polycrystalline samples.
