Ion-exchange reactions have been performed with 1D and 2D coordination polymers. 1D and 2D coordination polymers often have coordinated counterions which can be ion-exchanged for ions with either hydrogen bonding or Lewis basic sites. The 1D coordination polymer [Cu(H2O)3SO4(4,4’-bpy)] and the 2D coordination network [Co(pyrazine)2Cl2] have been examined for their ion-exchange properties. The new ions, such as 3-pyridinesulfonate and thiocyanate, are capable of hydrogen bonding or bridging to neighboring chains or networks. The products have been characterized by PXRD, FT-IR, DR-UV-Vis, and TGA, which reveal that the materials retain their crystallinity and show replacement of the ions.
