Fine-tuning of the reaction between alkali metal siloxanolate [PhSi(O)ONa]n and [Ni(NH3)6]Cl2 allowed us to design new hexa- [(PhSiO1,5)12(NiO)6(H2O)(DMSO)9] () and pentanuclear [(PhSiO1,5)10(NiO)5(NaOH)(DMF)7] () cage-like silsesquioxanes. Their specific structures were studied by single crystal X-ray diffraction and topological analyses. Compound is the first example of a pentanuclear "cylinder"-like metallasilsesquioxane. Magnetic property investigations demonstrate the presence of a slow relaxation of the magnetization, induced by spin glass-like behavior in both cases.
通过对碱金属硅醇盐[PhSi(O)ONa]n与[Ni(NH3)6]Cl2之间反应的微调，我们得以设计出新型的六核[(PhSiO1,5)12(NiO)6(H2O)(DMSO)9]（）和五核[(PhSiO1,5)10(NiO)5(NaOH)(DMF)7]（）笼状倍半硅氧烷。通过单晶X射线衍射和拓扑分析研究了它们的具体结构。化合物是首例五核“圆柱”状金属倍半硅氧烷。磁性研究表明，在这两种情况下，由自旋玻璃状行为诱导产生了缓慢的磁化弛豫。
