Structure of the defect perovskite Ce1/3NbO3: a redetermination by electron and neutron powder diffraction
Abstract
The crystal structure of the defect perovskite Ce1/3NbO3, cerium niobium oxide, has been re-examined by neutron powder and electron diffraction. The results of a powder neutron Rietveld refinement indicate that the structure is monoclinic: space group P2/m with Z = 4, a = 5.5267 (3), b = 7.8824 (2), c = 5.5245 (3) A, beta = 90.294 (1)degrees, V= 240.67 (2) A3 at 298 K with chi2 = 2.570. Previous reports have described the Ce1/3NbO3 structure in …
