  湿度控制的沉淀技术，可发现Rb 3（H 1.5 PO 4）2

  摘要：

  使用新开发的水相沉淀晶体生长变体，可以成功合成先前未知的化合物Rb 3（H 1.5 PO 4）2。该方法利用了浓溶液中沸点升高的现象。将化学计量的溶液在0.83 atm的高蒸汽分压下从110到150°C加热，即可获得标题化合物的晶体。单晶X射线衍射研究表明，Rb 3（H 1.5 PO 4）2在空间群C2 / m中结晶并且与Cs 3（H 1.5 PO 4）同构2。如通过热分析所证明的，Rb 3（H 1.5 PO 4）2在加热时不经历相变成三角超质子相。即使在蒸汽分压为0.82 atm的情况下，将脱水抑制到263°C的温度，也没有检测到多晶型转变。该行为与Cs 3（H 1.5 PO 4）2相似，并且与几种结构和化学上相似的硒酸盐化合物相反。这里开发的晶体生长方法可能证明对于获得在接近环境温度下热力学或动力学不利的水溶性化合物特别有用。

  摘要：

  AbstractThe control of noncarbon stereogenic centers is of profound importance owing to their enormous interest in bioactive compounds and chiral catalyst or ligand design for enantioselective synthesis. Despite various elegant approaches have been achieved for construction of S‐, P‐, Si‐ and B‐stereocenters over the past decades, the catalyst‐controlled strategies to govern the formation of N‐stereogenic compounds have garnered less attention. Here, we disclose the first organocatalytic approach for efficient access to a wide range of nitrogen‐stereogenic compounds through a desymmetrization approach. Intriguingly, the pro‐chiral remote diols, which are previously not well addressed with enantiocontrol, are well differentiated by potent chiral carbene‐bound acyl azolium intermediates. Preliminary studies shed insights on the critical importance of the ionic hydrogen bond (IHB) formed between the dimer aggregate of diols to afford the chiral N‐oxide products that feature a tetrahedral nitrogen as the sole stereogenic element with good yields and excellent enantioselectivities. Notably, the chiral N‐oxide products could offer an attractive strategy for chiral ligand design and discovery of potential antibacterial agrochemicals.

  sixth member of the family of M2n-2Mo6nX6n+2 structures (M=Rb, Cs; X=S, Se, Te), which contains Mo6n clusters, is represented by Rb10Mo36S38. The Mo36 cluster present in the title compound results from the uniaxial trans face sharing of eleven Mo6 octahedra, and forms a Mo36S44 cluster unit with 44 sulfur atoms of its environment (38 inner, 6 outer ligands). The large cavities between these units are
