Abstract

The rhodium complexes [RhCl3(NH3)3], (I), and [Rh(NO3)3(NH3)3], (II), are built from octahedral RhX3(NH3)3 units; in (I) they are isolated units, while in (II) the units are stacked in columns with partially filled sites for the Rh atoms. The octahedra of monoclinic crystals of (I) are linked by N-H···Cl hydrogen bonds and the Rh(3+) ions are located on the mirror planes. In the trigonal crystals of (II), the discontinuous `columns' along the threefold axis are linked by N-H···O hydrogen bonds. The structure of (I) has been solved using laboratory powder diffraction data, the structure of (II) has been solved by single-crystal methods using data from a merohedrally twinned sample. Both compounds possess low solubility in water.

从粉末数据和甲基三胺三氯化钠双晶中研究Rh3+离子的排列。

铑配合物[RhCl3(NH3)3]， (I)和[Rh(NO3)3(NH3)3]， (II)是由八面体RhX3(NH3)3单元构成的;在(I)中，它们是孤立的单元，而在(II)中，这些单元堆叠在具有部分填充的Rh原子位置的柱中。(I)单斜晶的八面体由N-H···Cl氢键连接，Rh(3+)离子位于镜面上。在(II)的三角晶体中，沿三轴不连续的“柱”由N-H···O氢键连接。(I)的结构用实验室粉末衍射数据求解，(II)的结构用单晶方法用单面孪晶样品的数据求解。这两种化合物在水中的溶解度都很低。

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.
