摘要

用甲烷磺酸和水在真空条件下沉淀法制备了一种新型甲烷磺酸铷盐（甲烷磺酸-κO）（甲烷磺酸-κO）（甲烷磺酸-κO）铷(I) [Rb(CH3SO3)(CH3SO3H)]。盐在单斜空间群C2/c （No. 15）中结晶。该结构是由由反平行的甲磺酸基桥接的交替边角共享双铷立方体组成的一维（1D）链。一维链通过氢键与相邻链紧密排列，两个甲磺酸单元在它们之间平均共享一个H原子。该低维结构具有5.4 eV的大带隙和210 nm的吸收边。

Crystal growth of an unusual salt derived from methanesulfonic acid: Rb(CH₃SO₃)(CH₃SO₃H).

Centimeter-sized crystals of a new rubidium methanesulfonic acid salt, (methanesulfonato-κO)(methanesulfonic acid-κO)rubidium(I), [Rb(CH₃SO₃)(CH₃SO₃H)], have been prepared via precipitation from methanesulfonic acid and water under vacuum. The salt crystallizes in the monoclinic space group C2/c (No. 15). The structure is comprised of one-dimensional (1D) chains of alternating edge- and corner-sharing dirubidium cuboctahedra bridged by antiparallel methanesulfonate groups. The 1D chains are tightly packed via hydrogen bonding to adjacent chains with the two methanesulfonate units sharing a single H atom equally between them. The low-dimensional structure has a large optical bandgap of 5.4 eV with an absorption edge of 210 nm.

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.
