|Resumen:||ZSM-5 (MFI code) is a medium-pore zeolite that has 10-ring channels with pore diameters of 5.1×5.5 and 5.3×5.6 Å, and has been a very successful zeolite for shape-selective catalysis that has found many industrial applications.|
By considering the structure of ZSM-5 and the catalytic results obtained in the fields of oil refining and petrochemistry, one could intuitively predict that a medium-pore zeolite with intersecting channels and pore dimensions that are slightly smaller than those of ZSM-5 should enhance the possibilities for shape-selective catalysis in the fields of fluid catalytic cracking (FCC) additives, catalytic dewaxing, toluene disproportionation, alkylation of aromatics, isomerization of alkylaromatics, and so forth.
Herein, we will describe such a zeolite structure (ITQ-13), which exhibits three sets of intercrossed medium-pore channels; a 9-ring channel, with a pore aperture of 4.0×4.9 Å, runs parallel to the crystallographic a axis, a 10-ring channel system (4.8×5.7 Å) runs parallel to the c axis, and another 10-ring set of channels (4.7×5.1 Å) runs parallel to the b axis.

Corrigendum text: "In the Communication “A Zeolite Structure (ITQ-13) with Three Sets of Medium-Pore Crossing Channels Formed by 9- and 10-Rings” by A. Corma et al. in Angew. Chem. 2003, 115, 1188–1191; Angew. Chem. Int. Ed. 2003, 42, 1156–1159, it should have been made clear early on in the manuscript that the synthesis of the ITQ-13 material was first reported in a patent published in 2002 (T. Boix, M. Puche, M. A. Camblor, A. Corma, US Patent 6 471941B1, 2002; reference  in the manuscript). Furthermore, owing to an editorial error the reference to this patent was wrongly introduced into the Experimental Section, where reference  should read reference  and viceversa. We apologize to our readers and to the authors of the above mentioned patent if this mistake has resulted in any misunderstanding".
