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.
通过单晶X射线衍射和拉曼光谱对水合黄原酸锂的晶体结构进行了研究，研究温度降至100K且压力增至5.3GPa。观察到在约4GPa处发生了相变。冷却过程中未发生相变。比较了晶格应变的各向异性和分子间相互作用的变化。
