Rietveld’s technique in combination with a continuous electron density representation was applied to structural modeling of highly ordered pure siliceous mesoporous mesophase material C16-SiO2-MMM of the MCM-41 type prepared by hydrothermal synthesis in the presence of C16H33N(CH3)3Br. Several important characteristics of the material in both as-synthesized and calcined forms were revealed. In particular, it was found that mesopores in the materials are of true hexagonal shape, and the wall electron density seems to be not continuous.
