Solid gold(I) fluoride remains as an unsynthesized and uncharacterized compound. We have performed a search for potential gold(I) fluoride crystal structures using USPEX evolutionary algorithm and dispersion‐corrected hybrid density functional methods. Over 4000 AuF crystal structures have been investigated. Behavior of the AuF crystal structures under pressure was studied up to 25 GPa, and we also evaluated the thermodynamic stability of the hypothetical AuF crystal structures with respect to AuF3, AuF5, and Au3F8. Mixed‐valence compound Au3[AuF4] with Au atoms in various formal oxidation states emerged as the thermodynamically most stable AuF species.

基于进化算法的氟化金(I)晶体结构预测。

固体氟化金(I)保留为未合成且未表征的化合物。我们使用USPEX进化算法和色散校正混合密度泛函方法对潜在的氟化金(I)晶体结构进行了搜索。已经研究了超过4000个AuF晶体结构。研究了在高达25 GPa的压力下AuF晶体结构的行为,我们还评估了假设的AuF晶体结构相对于AuF 3,AuF 5和Au 3 F 8的热力学稳定性。具有各种形式氧化态的Au原子的混合价化合物Au 3 [AuF 4 ]成为热力学上最稳定的AuF物质。
