Rubidium dicalcium triniobate(V), RbCa(2)Nb(3)O(10), has been synthesized by solid-state reaction and its crystal structure refined from X-ray powder diffraction data using Rietveld analysis. The compound is a three-layer perovskite Dion-Jacobson phase with the perovskite-like slabs derived by termination of the three-dimensional CaNbO(3) perovskite structure along the ab plane. The rubidium ions (4/mmm symmetry) are located in the inter-stitial space.
铷二钙三铌酸盐(V)，RbCa₂Nb₃O₁₀，通过固态反应合成，并使用Rietveld分析从X射线粉末衍射数据中精修其晶体结构。该化合物是一种三层钙钛矿Dion-Jacobson相，具有通过沿ab平面终止三维CaNbO₃钙钛矿结构而衍生的类钙钛矿板。铷离子（4/mmm对称性）位于间隙空间中。
