feature half‐sandwich rhodium(III) fragments at the vertices. Remarkably, a stable cage‐like heteropolymetallic complex possessing eight rhodium(III) and two silver(I) metal ions (3) has been obtained following a multistep procedure. The RhIII/AgI mixed macrocage enables the separation of dihalogenated benzene derivatives with high selectivity. Furthermore, a detailed X‐ray crystallographic study confirmed
已经准备了一系列金属超分子结构,包括矩形,棱柱形和笼形,在顶点具有半夹心的铑(III)片段。值得注意的是,通过多步法已获得了稳定的笼状杂多金属配合物,该配合物具有八个铑(III)和两个银(I)金属离子(3)。Rh III / Ag I混合巨笼能够以高选择性分离二卤代苯衍生物。此外,详细的X射线晶体学确认的辨别封装对-dihalobenzene(二氯苯,二溴苯和碘苯)由银-π相互作用和位阻效应的青睐。

One-dimensional (1D) coordination polymers, M(dhbq)·nH2O (M = Mg, Mn, Co, Ni, and Zn, H2(dhbq) = 2,5-dihydroxy-1,4-benzoquinone, n = 2, 2.5, or 3), were synthesized and their structures were investigated using the Rietveld refinement method. They have 1D structure and were isostructural. From water uptake measurements, thermogravimetry, and elemental analysis, new 2.5 hydrate states were discovered. The proton conductivity of M(dhbq) was found to depend on the metal species and the quantity of absorbed water.
