• Me(6)-diquat-5
• MCM-22(P) layered precursor

It is found that the layered precursor of a medium-pore zeolite MCM-22, frequently referred as MCM-22(P), which was initially formed in the presence of a flexible, linear diquaternary cation, N,N,N,N',N',N'-hexamethylpentanediammonium (Met(6)-diquat-5), and Na( ) is a reaction intermediate in the synthesis of another two medium-pore zeolites TNU-9 and EU-1. The overall results of this study reveal that the crystallization of the latter two zeolites under hydrothermal conditions at the expense of the Me(6)-diquat-5/MCM-22(P) composite material depends not only on the concentration of alkali metal cations in synthesis mixtures, but also on their type.
