ABSTRACT
A novel topology, consisting of a three-dimensional system of large pore channels, is found for the zeolite ITQ-7 (see picture). This material has been synthesized by combining the structure-directing effects of fluoride ions and a new organic cation purposefully designed to promote the crystallization of a low-density silica phase. ITQ-7 is the least dense crystalline silica phase known so far.
