Abstract

The previously reported structures of the hydrates of simple inorganic salts that crystallize at room temperature are generally well determined. This is not true for water-rich hydrates, which crystallize at temperatures below 273 K. In this series, investigations of the crystal structures of water-rich hydrates crystallized from aqueous solutions at low temperatures are presented. Reported herein are the structures of a set of magnesium salts. Crystals of MgCl2·8H2O (magnesium dichloride octahydrate), MgCl2·12H2O (magnesium dichloride dodecahydrate), MgBr2·6H2O (magnesium dibromide hexahydrate), MgBr2·9H2O (magnesium dibromide nonahydrate), MgI2·8H2O (magnesium diiodide octahydrate) and MgI2·9H2O (magnesium diiodide nonahydrate) were grown from their aqueous solutions at temperatures below 298 K according to the solid-liquid phase diagrams. All structures are built up from Mg(H2O)6 octahedra. Dimensions and angles in the hexaaqua cation complexes are very similar and variation is not systematic. The anions are incorporated into a specific network of O-H...X hydrogen bonds.

简单无机盐水合物的晶体结构。1 .富水卤化镁水合物为MgCl2·8H2O、MgCl2·12H2O、MgBr2·6H2O、MgBr2·9H2O、MgI2·8H2O和MgI2·9H2O。
以前报道的在室温下结晶的简单无机盐水合物的结构通常是确定的。但对于富水的水合物就不是这样了,它们在273 K以下的温度下结晶。在这个系列中,研究了从水溶液中低温结晶的富水水合物的晶体结构。本文报道了一组镁盐的结构。根据固液相图,在温度低于298 K的条件下,从水溶液中生长出MgCl2·8H2O(八水合二氯化镁)、MgCl2·12H2O(十二水合二氯化镁)、MgBr2·6H2O(六水合二溴化镁)、MgBr2·9H2O(非水合二溴化镁)、MgI2·8H2O(八水合二碘化镁)和MgI2·9H2O(非水合二碘化镁)晶体。所有的结构都是由Mg(H2O)6八面体构成的。六水阳离子配合物的尺寸和角度非常相似,变化不系统。阴离子结合到一个特定的O-H网络中。X氢键。

期刊介绍: Acta Crystallographica Section C: Structural Chemistry is continuing its transition to a journal that publishes exciting science with structural content, in particular, important results relating to the chemical sciences. Section C is the journal of choice for the rapid publication of articles that highlight interesting research facilitated by the determination, calculation or analysis of structures of any type, other than macromolecular structures. Articles that emphasize the science and the outcomes that were enabled by the study are particularly welcomed. Authors are encouraged to include mainstream science in their papers, thereby producing manuscripts that are substantial scientific well-rounded contributions that appeal to a broad community of readers and increase the profile of the authors.
