摘要
通过水热法获得了一种新的铀硅酸盐 Cs4[(UO2)5(SiO3OH)2O2F4] (1)。新化合物呈单斜型，P21/n，a = 8.3870(2)，b = 13.4612(2)，c = 10.9503(2)埃，β = 91.223(2)°，V = 1236.00(4) Å3；该结构已被求解并细化至 R 1 = 0.022。其中，磷酰单位（PUs）结合成一种新型的铀硅酸盐层，即[(UO2)5(SiO3OH)2O2F4]4-，与 Cs+ 阳离子交错。对基于 PU 的结构进行的拓扑分析表明，1 中的这些层是仅通过 PU 关联而不涉及其他构建单元构建复合物的独特实例。
A new uranyl silicate sheet derived from phosphuranylite topology in the structure of Cs4[(UO2)5(SiO3OH)2O2F4]
A new uranyl silicate Cs4[(UO2)5(SiO3OH)2O2F4] (1), was obtained via a hydrothermal route. The new compound is monoclinic, P21/n, a = 8.3870(2), b = 13.4612(2), c = 10.9503(2) Å, β = 91.223(2)°, V = 1236.00(4) Å3; the structure has been solved and refined down to R1 = 0.022. Therein, the phosphouranylite units (PUs) associate into a new type of uranyl-silicate layers, [(UO2)5(SiO3OH)2O2F4]4−, which interleave with the Cs+ cations. Topological analysis of PU based structures indicates that these layers in 1 provide a unique example of complexes constructed only via association of the PU and not involving other building units.
