The three-dimensional (3D) coordination polymers [Cd(tpmd)(NCX)] [X = O (), S (), and BH (); tpmd = ,,','-tetrakis(pyridin-4-yl)methanediamine] have been determined to display their network structures through coordinated anionic ligands. Polymers and show nonporous structures, whereas polymer shows a porous coordination framework. On the basis of the Cd(II) network structures, the 3D coordination polymer [Zn(tpmd)(NCBH)]·MeOH () was self-assembled. In the cases of polymers and , pseudohalide ions acted to form nonporous network structures; however, in polymers and , NCBH helps to construct porous network structures. Polymers - show strong ultraviolet luminescence emissions, depending on the pseudohalide ions present, compared to the tpmd ligands. Interestingly, coordination polymers and that possess NCBH ions exhibit high porosities and gas sorption properties. The polymers appeared to absorb N, H, CO, and CH. In the case of polymer , the structure is almost identical with that of polymer , except for the Cd(II) ion. However, polymer has a larger void volume and higher gas absorption ability for N gas than polymer . For the sorption of gases, polymers and showed similar behaviors.
