New alkaline earth metal-based coordination polymers with zeolitic ABW, ACO, and chiral (10,3)-a topologies

• Five alkaline earth metal-based coordination polymers were prepared.
• Magnesium carboxylates have zeolitic ABW and ACO topologies.
• Three coordination polymers have a chiral (10,3)-a topology.

A series of alkaline earth metal-based coordination polymers, Mg(ndc)(H2O)·py (1), (Hpy)2·Mg3(ndc)4(H2O)2(py)2 (2), and M(ndc)(dmf) [M = Ca (3), Sr(4), Ba(5)], have been prepared under solvothermal conditions. Compound 1 has a neutral framework with a zeolitic ABW topology. Compound 2 has an anionic framework with a zeolitic ACO topology. Compounds 3–5 are isostructural and possess a neutral framework with a chiral (10,3)-a topology. The thermal stability, fluorescent properties, and SHG responses of compounds 3–5 have also been investigated.

A series of alkaline earth metal-based coordination polymers have been synthesized. These compounds display different structures with zeolitic ABW, ACO, and chiral (10,3)-a topologies, respectively.Figure optionsDownload as PowerPoint slide
