Abstract
Two uranyl-organic hybrid compounds were self-assembled from the reaction of uranyl cations with 1,4-phenylenebis(methylidyne)tetrakis(phosphonic acid) in the presence of alkali metal cations (Rb+ and Cs+): Rb0.40{(UO2)2[(H0.90O3P)2CH–C6H4–CH(PO3H0.90)2](H2O)2} (1) and [Cs0.33(H2O)2]2{(UO2)2[(H0.67O3P)(HO3P)CH–C6H4–CH(PO3H)(PO3H0.67)](H2O)2} (2). Compound 1 consists of chains of UO7 pentagonal bipyramids linked by the tetrakisphosphonate moieties into two-dimensional layered networks. In compound 2, the –CH(PO3)2 groups chelate the uranyl centers in an exclusively bidentate mode, forming corrugated chains within a uranyl-tetrakisphosphonate framework. In both structures, the uranyl tetrakisphosphonate sheets are stabilized by weak intermolecular forces and noncovalent interactions involving water molecules and alkali metal ions.
期刊介绍：
The aim of Crystal Growth & Design is to stimulate crossfertilization of knowledge among scientists and engineers working in the fields of crystal growth, crystal engineering, and the industrial application of crystalline materials.
Crystal Growth & Design publishes theoretical and experimental studies of the physical, chemical, and biological phenomena and processes related to the design, growth, and application of crystalline materials. Synergistic approaches originating from different disciplines and technologies and integrating the fields of crystal growth, crystal engineering, intermolecular interactions, and industrial application are encouraged.
