title: RbCa(2)Nb(3)O(10) from X-ray powder data.
abstract: 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.
