| Abstract: | The distribution and structure of selenium nanoclusters synthesized in crystals of the porous silica ZSM-11 are investigated using the maximum-entropy method and the Rietveld analysis. It is demonstrated that the intercalated selenium atoms are arranged in channels of the ZSM-11 zeolite in the form of scraps of infinite chains similar to those observed in massive selenium. The distances between the nearest neighbor selenium atoms vary in the range 2.53–2.70 Å. |
