摘要
通过单晶 X 射线衍射和拉曼光谱研究了水合黄原酸锂在冷却至 100 K 和压缩至 5.3 GPa 时的晶体结构。在 ∼4 GPa 处观察到相变。冷却时没有发生相变。比较了晶格应变的各向异性和分子间相互作用的变化。
A comparative study of the effect of high-pressure and low temperature on the crystal structure of lithium xanthinate hydrate.
The crystal structure of lithium xanthinate hydrate was studied by single crystal X-ray diffraction and Raman spectroscopy on cooling to 100 K and under compression to 5.3 GPa. A phase transition at ∼4 GPa is observed. No phase transitions occur on cooling. Anisotropy of lattice strain and changes in intermolecular interactions are compared.
期刊介绍:
Acta Crystallographica Section B: Structural Science, Crystal Engineering and Materials publishes scientific articles related to the structural science of compounds and materials in the widest sense. Knowledge of the arrangements of atoms, including their temporal variations and dependencies on temperature and pressure, is often the key to understanding physical and chemical phenomena and is crucial for the design of new materials and supramolecular devices. Acta Crystallographica B is the forum for the publication of such contributions. Scientific developments based on experimental studies as well as those based on theoretical approaches, including crystal-structure prediction, structure-property relations and the use of databases of crystal structures, are published.
