Growth of interest to a field of materials chemistry such as the metal-organic frameworks (MOFs) demands the comprehensible surveying of new results, and the reviews systematizing and highlighting one or another trend in the MOF research appear periodically. Structural peculiarities of coordination polymers constructed by zinc paddle-wheel clusters and the investigation of their microporosity are reviewed in detail to emphasize those features of the materials, which are interesting both for the pure and applied chemists.
