Abstract

The zinc tetraammine complexes [Zn(NH₃]₄]F₂ (ZAF) and [Zn(NH₃]₄](NO₃)₂ (ZAN) have been isolated from methanolic ammonia and characterized by single crystal X-ray diffraction and Raman spectroscopy. As determined from Raman data, the tetrahedral structure of the zinc tetraammine cation complex is sustained in solutions that contain high concentrations of ammonia. Dilution of ZAF or ZAN solutions in bulk water results in the deposition of ZnO as determined by X-ray powder diffraction (XRD). Lower dilution, as when aqueous ZAF is applied to wet surfaces, results in Zn(OH)F deposition as identified by XRD. These mineral products are readily obtained from zinc tetraammine solutions under ambient conditions and lend themselves to biomedical and materials applications.

在环境条件下四胺二氟化锌和二硝酸锌的形成及其向氧化锌和羟基氟化锌的转化

我们从甲醇氨水中分离出了锌四胺络合物 [Zn(NH3]4]F2 (ZAF) 和 [Zn(NH3]4](NO3)2 (ZAN)，并利用单晶 X 射线衍射和拉曼光谱对其进行了表征。根据拉曼数据确定，锌四胺阳离子复合物的四面体结构在含有高浓度氨的溶液中得以维持。根据 X 射线粉末衍射（XRD）的测定，在散装水中稀释 ZAF 或 ZAN 溶液会导致氧化锌沉积。稀释程度较低时，如将ZAF水溶液涂抹在潮湿的表面上，则会出现 XRD 所确定的 Zn(OH)F 沉积。在环境条件下，很容易从四氨化锌溶液中获得这些矿物产品，并将其应用于生物医学和材料领域。

期刊介绍： Inorganica Chimica Acta is an established international forum for all aspects of advanced Inorganic Chemistry. Original papers of high scientific level and interest are published in the form of Articles and Reviews. Topics covered include: • chemistry of the main group elements and the d- and f-block metals, including the synthesis, characterization and reactivity of coordination, organometallic, biomimetic, supramolecular coordination compounds, including associated computational studies; • synthesis, physico-chemical properties, applications of molecule-based nano-scaled clusters and nanomaterials designed using the principles of coordination chemistry, as well as coordination polymers (CPs), metal-organic frameworks (MOFs), metal-organic polyhedra (MPOs); • reaction mechanisms and physico-chemical investigations computational studies of metalloenzymes and their models; • applications of inorganic compounds, metallodrugs and molecule-based materials. Papers composed primarily of structural reports will typically not be considered for publication.
