In the presence of PPhMe cations, Kemp's tricarboxylate (kta) complexes the uranyl cation to give [PPhMe][UO(kta)] (1), a triperiodic framework with cubic symmetry and srs topology. The PPhMe cation is held by weak interactions into cavities with matching three-fold rotational symmetry. Comparison with the diperiodic hemi-hydrate polymorph previously reported points to the disrupting role of OHO hydrogen bonds in the latter.
在三甲基苯基鏻阳离子存在的情况下，坎普三羧酸（kta）与铀酰阳离子络合，生成[三甲基苯基鏻][铀酰（kta）]（1），这是一种具有立方对称性和srs拓扑结构的三周期框架结构。三甲基苯基鏻阳离子通过弱相互作用被保持在具有匹配三重旋转对称性的空腔中。与先前报道的二周期半水合物多晶型物相比，表明后者中OHO氢键的破坏作用。
