Metal-organic networks

The structural richness and diversity of the metal-organic networks obtained by reaction of Cul and CuBr with ArSC4SAr (C4 = (CH2)4, CH2C=CCH2) are summarized in Scheme 10. 

Catalysis by metal-organic solids may also be applied to redox reactions. An especially intriguing target would be manipulation of hydrocarbon transformations. Many metal-organic networks so far reported in fact contain redox-active transition metals (Cu , Pd", Co" and so on). Metalloporphyrins are potential... 

Scheme 4 illustrates some of the 2-D network motifs that have thus far been observed in coordination polymers. Square-grid networks (Scheme 4a) exemplify a particularly simple and commonly reported example of a predictable 2-D metal-organic network. Square-grid coordination polymers are based upon 1 2 metahligand complexes with linear bifunctional linkers. Grids with two tjmes of linkers have also been reported, in which rectangular grids are formed (Scheme 4c). ... 

Conformational flexibility in ligands can lead to conformational snpramolecular isomers in metal-organic network systems. For example, hydrothermal crystallization using an aminotriazole ligand afforded two 3D supramolecular...
