摘要

Structural property of polycrystalline La_(1.9)Bi_(0.1)Mo_2O_(9-δ) has been investigated. Rietveld refinement at room temperature of the material suggests single phase nature with cubic symmetry (space group P2_13). The electron charge density contour map has been successfully obtained from Rietveld analysis. It has been found that oxygen ion migration is favourable for (210) plane than (63-1) and (110) planes.
