锌赤铁矾的晶体结构
CRYSTAL STRUCTURE OF ZINCOBOTRYOGEN
【摘要】 锌赤铁矾是1964年在我国首次发现的一种硫酸盐类新矿物。它的实验化学式是(Zno0.64Mg0.27Mn0.11Fe0.052+)1.07Fe1.003+(SO4)1.96(OH)·6.61H2O,理论分子式为ZnFe3+(SO4)2(OH)·7H2O。本文在前人工作的基础上,利用四圆衍射仪对其结构进行了精测。根据所得实验资料,着重对如下晶体化学问题做了讨论;(1)氢键;(2)多面体的畸变;(3)原子的热运动;(4)结构和物性的关系;(5)Zn2+和Mg2+的类质同象等。同时,对锌赤铁矾的某些谱学特征和它与类同矿物的关系做了对比和讨论。
【Abstract】 Zincobotryogen is a new sulphate mineral with an experimental formula of (Zn0.64Mg0.27Mn0.11Fe0.052+)1.07Fe1.003+(SO4)1.06)(OH)·6.61H2O and a theoretical formula of ZnFe3+(SO4)2(OH)·7H2O, which was found in China in 1964. Based on the previous work, its crystal structure was examined with a four-circle diffractomelet, and the following crystallochemieal problems were discussed in this papers (Ⅰ) hydrogen bond; (2) distortion of polyhedra; (3) thermal vibrations of atoms; (4) relationship between structure and physical properties; and (5) replacement of Mg by Zn. Besides, the interpretation of some spectral characteristics of zincobotryogen and the comparison between this mineral and other Similar minerals were also made.
