Bridged Coordination Polymers

A number of cyano-bridged coordination polymers with Prussian Blue-related structures, in which extended linear Ag(CN)2 or AufCNH bridges take the place of the OT bridges of the prototype, show 3-fold interpenetration [1]. A typical example is that of Rb[Cd Ag(CN)2)3] consisting of Rb+ cations and a 3-fold interpenetrating polymeric anion, whose structure is shown in Figure 31. 

Prussian blue was the first coordination polymer and has found extensive applications as a dye and ink. It has inspired the related Hoffman clathrates which are also CN bridged coordination polymers. In contrast Werner clathrates are based on discrete coordination complexes as the host but they do display some of the robustness of coordination polymers.

When the assembly process involves hexacyanometallates and fully solvated metal ions, Prussian-blue phases are obtained, which are cubic 3D networks. Figure 33 shows the crystal structure of such a 3D cyano-bridged coordination polymer NaMnCr(CN)6- ...
