制备方法与用途

理化性质

是一种无色针状晶体或白色粉末,有两种形态:无物和四水合物。与其他卤化不同,它具有明显的离子键化合物特性,熔点高且溶解度较小。的晶型为红石型结构,其中原子以六配位的形式存在;而四水合物则属于菱方晶系。此外,结晶体还能使光线强烈偏振。

该物质难溶于,几乎完全不溶于液乙醇,微溶于稀氢氟酸,并且略溶于盐酸硝酸氨水。其溶液极易发生解反应,生成碱式盐 Zn(OH)F。

在加热条件下与氢气共热时,会被还原: [ \text{ZnF}_2 + \text{H}_2 \rightarrow \text{Zn} + 2\text{HF} ]

用途

含有部分结晶是一种重要的荧光剂。然而,无水氟化锌不具备这一特性。工业上,用作陶瓷釉和涂料、催化剂以及木材防剂,并且还用于有机化合物的化反应。

    An infrared study of the stretching modes of the water molecules in ZnF2·4H2O
    摘要:
    The IR spectra of ZnF2.4H2O and its deuterated analogues are reported at ambient and liquid-nitrogen temperatures. The O-H and O-D stretching and bending vibrations of the water molecules are analysed in detail. The two types of water molecules give rise to different absorption peaks in the O-H and O-D stretching regions in samples that contain isotopically dilute HDO groups. The strongly hydrogen-bonded water molecules H2O(1) and H2O(4) show four broad O-H and O-D stretching modes at lower frequencies, while the weaker hydrogen-bonded ones H2O(2) and H2O(3) give rise to four narrow bands at higher frequencies. The nu(OD) frequencies of isotopically dilute HDO groups correlate very well with the known R(H---F) and R(H---O) distances in the crystals and the assignment of these modes was done on this basis. It was also found that the ratio nu(OH)/nu(OD) decreases with decreasing values of R(H---O) or R(H---F) in ZnF2.4H2O.

  • From ZnF<sub>2</sub> to ZnF<sub>2</sub>(H<sub>2</sub>O)<sub>4</sub>: Partial Substitution Achieves Structural Transformation and Nonlinear Optical Activity while Keeping Short Ultraviolet Cutoff Edge

    Exploring nonlinear optical (NLO) materials with short ultraviolet cutoff edges are significant for developing an all-solid-state laser. Here, a noncentrosymmetric zinc fluoride hydrate, ZnF2(H2O)4, was synthesized by a hydrothermal method. It crystallizes in the polar space group of Pca21. The compound consists of the central Zn2+ combined with F– and coordination water to form the [ZnF2(H2O)4] octahedra
    探索具有短紫外截止边缘的非线性光学(NLO)材料对于开发全固态激光器具有重要意义。这里,通过热法合成了非中心对称合物ZnF 2 (H 2 O) 4 。它在Pca 2 1极性空间群中结晶。该化合物由中心Zn 2+与F -和配位结合形成[ZnF 2 (H 2 O) 4 ]八面体,每个八面体相互隔离,形成0维结构。作为无心化合物,ZnF 2 (H 2 O) 4显示出相位匹配的二次谐波产生(SHG)活性,其强度约为KH 2 PO 4的0.5倍。更有吸引力的是,它还显示出低于 200 nm 的短紫外线截止边缘,这在已报道的卤化物合物体系中很少见。有趣的是,从ZnF 2到ZnF 2 (H 2 O) 4 ,配位的F原子被H 2 O分子部分取代,导致结构从有心到无心的转变,SHG活性从关闭到开启。这项工作介绍了结构分析、非线性光学活动和理论计算。
