A reinvestigation of the structure of Cs₃Ta₅O₁₄

D. du Boulay, A. Oono and N. Ishizawa

Abstract: In a recent analysis of a new pyrochlore-like mesoporous phase Rb₃Ta₅O₁₄ (trirubidium pentatantalum tetradecaoxide) [du Boulay et al. (2002). Acta Cryst. C58, i40-i44], the authors observed in the literature some rather large uncertainties in the vibrational motion and thereby atomic positions reported for the archetypal analogue structure Cs₃Ta₅O₁₄. New X-ray diffraction data for that compound were collected on an image plate diffractometer with an Mo K source. The current study confirms the original structural model and modestly improves on its precision.
