Presented herein is the crystal-structure redetermination of LiZrF from single-crystal X-ray data. Alkali zirconium fluorides are important in nuclear-relevant technologies, and zirconium is commonly employed as an analogue for tetra-valent -block elements. The previous structure report of this species is based on powder X-ray data [Dugat (1995 ▸). , 187-196] but there has never been a refined structure model from single-crystal data. The octa-fluorido-zirconate moieties are held together by electrostatic attraction to lithium ions without sharing of fluoride sites between zirconium(IV) ions.
本文介绍了通过单晶X射线数据对LiZrF进行的晶体结构重新测定。碱金属锆氟化物在与核相关的技术中很重要，并且锆通常被用作四价锕系元素的类似物。该物种先前的结构报告基于粉末X射线数据[杜加特（1995▸），，187 - 196]，但从未有过基于单晶数据的精确结构模型。八氟锆酸根部分通过与锂离子的静电吸引结合在一起，锆（IV）离子之间不共享氟位点。
