Abstract A new layered silicate has been synthesized in the quaternary system Na2O−SiO2−H2O-polymeric organic cation. The polymeric organic cation was intercalated into the silicate during crystallization. Composition, structure, and x-ray diffraction pattern of the new silicate do not fit with any known layered silicate [1–5]. Many similarities were found to hydrous alkali silicates (metal silicate hydrates, M-SH-type). The new silicate differs from M-SH by a high structural stability, against a wide range of different energetic influences. Due to the relatively high stability, high-resolution electron microscopy (HREM) can be applied to study the layer structure of this silicate as a representative of the M-SH silicates. All known M-SH, for example, magadiite and kenyaite are decomposed by the electronic beam.
