Local structure of the layered superconductor g-Mo 3 C 2 (T c = 8.5 K) was studied by a neutron diffraction method. The structure comprises a triangular-lattice layer and a block layer, and the layers share a common structure basis of octahedral CMo 6 . We found that the block layer contains non-tri
X-ray diffraction analysis, using the Rietveld refinement method, of samples of the NaxWO3 system for 0.2 ~< x~< 0.4, prepared at 900Β°C, shows that for x>/0.28 the samples are a mixture of two phases: one with tetragonal crystalline structure and space group P4/mbm, and the other with cubic crystall
