We report on the systematic exploration of zeolite synthesis using a combination of organic molecules of different size. The effect of changing the co-structure directing agent, co-SDA, (tetramethylammonium or quinuclidine) and its replacement by sodium cations, when used together with the bulky organic cation 1-benzyl-1-methylpyrrolidinium (bmp) is analyzed and compared with preparations where bmp is replaced by the related cation (S)-1-benzyl-2-hydroxymethyl-1-methylpyrrolidinium (bmprol). The tendency to direct the synthesis to ferrierite or ferrierite-like materials depending on the particular combination of bulky organic cation and co-SDA is discussed. The catalytic activity of some of the materials synthesized was tested in the isomerization of m-xylene.
