Metal-organic frameworks based on trigonal prismatic building blocks and the new "acs" topology.

چکیده
Cationic and mixed-valent forms of Fe3O(CO2)6 trigonal prismatic clusters have been linked by ditopic links, namely, 1,4-benzenedicarboxylate (1,4-BDC) and 1,3-benzenedicarboxylate (1,3-BDC), to produce two 3-periodic metal-organic frameworks (MOFs), [Fe3O(1,4-BDC)3 (DMF)3][FeCl4] x (DMF)3 (MOF-235) and Fe3O(1,3-BDC)3 (py)3 x (py)0.5(H2O)1.5 (MOF-236) (DMF = N,N-dimethylformamide, py = pyridine), respectively. These MOFs exemplify a new, high-symmetry topology termed acs which we identify here as the default arrangement for linking trigonal prisms together.

Network diversity through decoration of trigonal-prismatic nodes: two-step crystal engineering of cationic metal-organic materials.
During the past decade porous metal–organic material (MOM) networks constructed from metal-based nodes (metal ions or metal clusters) and bridging organic ligand (linkers) have attracted ever increasing scientific interest. Their modular nature imparts structural and compositional diversity, tunable functionality, and multiple properties within a single material. In particular, that MOMs can ex...

This review details the emergence of metal–organic materials (MOMs) sustained by high symmetry trigonal prismatic molecular building blocks (MBBs). MOMs have attracted general attention over the past two decades as judicious selection of MBBs allows crystal engineers to exert exquisite control over MOM structure, which, when combined with their modularity, diverse composition and fine-tuneable ...

Metal–organic materials (MOMs) assembled from metalbased or organic molecular building blocks (MBBs) and organic linkers have attracted increasing scientific interest during the past decade. Their structure (especially their modularity) and properties (especially extra-large surface area) have made them an attractive class of porous materials for applications including gas purification and stor...
متن کاملElectronic Structure Modulation of Metal–Organic Frameworks for Hybrid Devices
The study of metal-organic frameworks has largely been motivated by their structural and chemical diversity; however, these materials also possess rich physics, including optical, electronic, and magnetic activity. If these materials are to be employed in devices, it is necessary to develop an understanding of their solid-state behavior. We report an approach to calculate the effect of strain o...
