Two Principles of Reticular Chemistry Uncovered in a Metal-Organic Framework of Heterotritopic Linkers and Infinite Secondary Building Units.

Metal-organic frameworks of cobalt and nickel centers with carboxylate and pyridine functionality linkers: Thermal and physical properties; precursors for metal oxide nanoparticle preparation

This  article  provides  an  overview  on  preparation,  design,  crystal structure  and  properties  of  some  metal-organic  frameworks  of carboxylate coordination polymers mixed with pyridine-functionality linkers  prepared  in  our  laboratory.  The  article  covers  coordination polymers  in  two-  and  three-dimensional  supramolecular architectures. The reported coordination polyme...

Crystalline fibers of metal-peptide double ladders.

Despite remarkable progress in the field of MOFs, structures based on long-flexible organic linkers are scarce and the majority of such materials rely on rigid linkers. In this work, crystals of a new metal-organic double ladder (MODL) are obtained by linking a pentapeptide (NH2-Glu-pCO2Phe-pCO2Phe-Ala-Gly-OH) with cadmium acetate to produce a Cd(2-pyrrolidone-pCO2Phe-pCO2Phe-Ala-Gly)(H2O)3 fra...

Modular chemistry: secondary building units as a basis for the design of highly porous and robust metal-organic carboxylate frameworks.

Secondary building units (SBUs) are molecular complexes and cluster entities in which ligand coordination modes and metal coordination environments can be utilized in the transformation of these fragments into extended porous networks using polytopic linkers (1,4-benzenedicarboxylate, 1,3,5,7-adamantanetetracarboxylate, etc.). Consideration of the geometric and chemical attributes of the SBUs a...

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

Reticular chemistry of metal-organic polyhedra.

Metal-organic polyhedra (MOPs), are discrete metal-organic molecular assemblies. They are useful as host molecules that can provide tailorable internal volume in terms of metrics, functionality, and active metal sites. As a result, these materials are potentially useful for a variety of applications, such as highly selective guest inclusion and gas storage, and as nanoscale reaction vessels. Th...
