Rectangular grid networks

Mak and co-workers have shown how the ligands 1 and 2 react with Cu(II) to form a rectangular grid network of dimensions 6.83 x 11.15 A (Figure 11) [29], The Cu atom adopts an elongated octahedral geometry with two moieties of 1 and two... 

In this context, MichaeUdes and coworkers were the first to describe a photoreaction integrated into a MOF. The framework was based on Cd(II) ions connected to fiun ions that produced a rectangular grid network (Figure 11). The C=C bonds were parallel and separated by 3.37 A between adjacent layers, which enabled the olefins to react to give cbta. Although the network did not possess cavities, the study established that reactive components can be incorporated into a MOF.

Note that the C-H O bonded and benzene layers are parallel to each other but perpendicular to grid planes. 

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). ...
