Synthesis, Crystal Structure and Gas Adsorption Properties of Four Pd-Zn Coordination Polymers Containing Potential Catalytic Active Sites
New Pd–Zn coordination polymers incorporating a PdII complex were prepared in one‐pot reactions from isonicotinic acid, K2[PdCl4] and ZnII ions in water. Depending on the reaction conditions, four new types of Pd–Zn coordination polymers (one‐, two‐ and three‐dimensional networks), which consist of...

Summary: | New Pd–Zn coordination polymers incorporating a PdII complex were prepared in one‐pot reactions from isonicotinic acid, K2[PdCl4] and ZnII ions in water. Depending on the reaction conditions, four new types of Pd–Zn coordination polymers (one‐, two‐ and three‐dimensional networks), which consist of a PdII complex coordinated by two or four isonicotinic acids, were formed. The structures were determined by single‐crystal X‐ray diffraction, X‐ray powder diffraction, TGA and CHN elemental analysis. Interestingly, for the N2 and H2 gas adsorption measurements at 77 K and 760 Torr, two of the new Pd–Zn coordination polymers show selective H2 gas adsorption performances. Therefore, these complexes may be potentially attractive materials for heterogeneous catalysts or for H2 gas separation for hydrogenation reactions.
Four new Pd–Zn coordination polymers have been synthesized by slow concentration or solvothermal methods, and structurally characterized. Two of the four Pd–Zn coordination polymers showed selective H2 gas adsorption over N2 gas adsorption at 77.35 K and 760 Torr. |
