Graphical Abstract

A void in the issue: A one-step self-assembly of γ-Keggin sandwich-type silicotungstates with M2Zn2 (M=Co, Ni, Zn) tetranuclear cores and tetrabutylammonium cations gave porous ionic crystals. These porous crystals are hollow frameworks containing large voids (ca. 38×38×38 Å3, see picture, voids yellow), between which guest molecules can be exchanged through the connecting channels.
