Reticular Chemistry of Metal-Organic Frameworks Composed of Copper and Zinc Metal Oxide Secondary Building Units as Nodes

This contribution details the reticular chemistry approach in which inorganic secondary building units (SBUs) are linked with organic struts into robust, extended metal–organic frameworks (MOFs). Inorganic SBUs, derived from copper and zinc, are diverse since they adopt various cluster geometries, which enable the formation of structurally diverse nets. Simple geometrical principles based on the direct joining of polyhedral or polygonal nodes propagate SBUs into frameworks with often predictable topology and structure. Herein, we classify the copper and zinc nodes according to their points of extension and detail the most relevant SBUs in this context. In addition, at least one prominent MOF example is provided in each section as a representation for the broader class of isoreticular (of the same net) materials.
