Abstract
The crystal structures of the double perovskites Ba2CePbO6, Ba2PrPbO6, and Ba2TbPbO5.90 have been refined by Rietveld analysis of time-of-fl ight neutron powder diffraction data. All three phases contain complet ely disordered B-cations. Diffraction and chemical analysis data indic ate that Ba2TbPbO5.90 is slightly oxygen deficient.
