Four new coordination polymers based on carboxyphenyl-substituted dipyrazinylpyridine ligand: Syntheses, structures, magnetic and luminescence properties

Four new coordination polymers based on carboxyphenyl-substituted dipyrazinylpyridine have been synthesized by changing metal ion and introducing auxiliary ligand under hydrothermal conditions. Compounds 1, 3 have similar structures which show infinite wave chains and compounds 2, 4 display infinite ladder chains. Additionally, photoluminescence and magnetic properties of 1-4 have been investigated.
