A single crystal of Nd 5 Mo 3 O 16 with lead partly substituting for neodymium, which has a fluorite‐like structure, was studied by precision X‐ray diffraction, high‐resolution transmission microscopy and EDX microanalysis. The crystal structure is determined in the space group . It was found that the Pb atoms substitute in part for Nd atoms in the structure and are located in the vicinity of Nd2 positions. Partial substitutions of Mo cations for Nd positions and of Nd for Mo positions in crystals of the Ln 5 Mo 3 O 16 oxide family are corroborated by X‐ray diffraction for the first time. The first experimental verification of the location of an additional oxygen ion in the voids abutting MoO 4 tetrahedra was obtained.
