The spiro‐5 building block 1 is an unusual arrangement of five [TO 4 ] tetrahedra (T Si, Zn) to give two three‐rings of tetrahedra. This building unit is the backbone of the partial structure of the tetrahedral framework of the new zincosilicate zeolite 2 . The nonframework components Na + , K + , and H 2 O likewise form a three‐dimensional network, which contributes considerably to the stability of 2 .\documentclass{article}\usepackage{amssymb}\pagestyle{empty}\begin{document}$${\rm K}_4{\rm Na}_{12}[{\rm Si}_{28}{\rm Zn}_8{\rm O}_{72}]\cdot 18{{\rm H}_2{\rm O}}\quad {\bf 2}$$\end{document}
