Porous coordination polymers with zeolite topologies constructed from 4-connected building units

Two novel 3D coordination polymers, Cd(CTC)(H2O)center dot (H2PIP)(0.5)(H2O) (1) with zeolite ABW topology and Cd(CTC)center dot(HIPA) (2) with zeolite BCT topology, have been synthesized by constructing inorganic and organic 4-connected building units and using the organic bases as templates, and the frameworks of 1 and 2 not only expand the original structures of zeolites ABW and BCT, but also exhibit significant advantages over them in terms of thermal stability, ion exchange and adsorption.
