TNU-7: A Large-Pore Gallosilicate Zeolite Constructed of Strictly Alternating MOR and MAZ Layers

The structure solution of TNU-7 (Taejon National University number 7), a large-pore gallosilicate zeolite constructed of strictly alternating MOR and MAZ layers, is presented. This “boundary phase” zeolite was synthesized without recourse to organic additives in a crystallization field surrounded by those of the structurally related MAZ and MOR zeolites.
