Z.-H. Liang, K.-B. Tang, Q.-W. Chen and H.-G. Zheng

Abstract: Rubidium dicalcium triniobate(V), RbCa₂Nb₃O₁₀, 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 CaNbO₃ perovskite structure along the ab plane. The rubidium ions (4/mmm symmetry) are located in the interstitial space.
