Ligand-directed strategy for zeolite-type metal-organic frameworks: Zinc(II) imidazolates with unusual zeolitic topologies

(Figure Presented) Thermally robust porous metal-organic frameworks (MOFs) with zeolitic topologies were constructed by means of a ligand-directed strategy involving molecular tailoring of simple bridging imidazolates with coordinatively unimportant substituents. This led to the isolation of three new MOFs having unusually high symmetries, intriguing topologies such as the supercage shown in the picture, and high thermal stability. © 2006 Wiley-VCH Verlag GmbH & Co.
