Cyanides bridging ligands

Unlike the discrete molecular complexes described above, many compounds with bridging cyanide ligands are three-dimensional coordination polymers. The classic example of this type of compound is Pmssian blue, [Fe4 Fe(CN)6 3]-xH20 (13), whose intense color arises from an intervalence transfer transition see Intervalence Transfer Transition) from low-spin Fe + to high-spin Fe +... 

In this work, metal ions have been reacted with hexacyanometallates systematically to synthesize a series of PB compounds. Characterization of these samples has been performed with Infrared spectroscopy, since bridging cyanide ligands of PB systems exhibit distinctive peaks at 2000-2200 cm . The crystal structure of samples have been confirmed with powder XRD analysis. Finally, the CO2 adsorption capacity of these samples will be measured using magnetic suspension sorption device.
