A new route for the syntheses of coordination polymers using magnetic influence: syntheses, crystal structures and fluorescence properties.

ABSTRACT: Five coordination polymers [TM¹(absa)(H₂O)₄]_n and [TM²(absa)(bipy)(H₂O)]_n [TM¹ = Zn (1), Co (2); TM² = Zn (3), Co (4), Cu (5); Na₂absa = 5,5'-azobissalicylic acid disodium salt; bipy = 4,4'-bipyride] were synthesized by solvent evaporation under a magnetic field. It is evident that magnetic fields bring significant and noticeable changes to the absa^2- ligand orientation and the component movement behaviors to construct coordination polymers. The absa^2- ligands bind to the metal ions in bridging coordination mode through the carboxylate groups, in addition to the bipy molecules adopting bridging modes. Photoluminescence measurements indicate that the emissions
