| Abstract: | Two new coordination polymers, [Na(H2L)(H2O)2]n ( 1 ) and [Ba(H2L)2(H2O)]n ( 2 ) (H3L = 3‐formyl‐4‐hydroxybenzenesulfonic acid) were synthesized and structurally characterized. The H2L– ligand shows three different bridging modes, μ3 in 1 , μ3 and μ4 in 2 . Compound 1 presents a 2D pillared structure, whereas 2 forms a 3D framework. Both 1 and 2 show blue luminescence at 380 nm in aqueous solution, however, their solid state emissions are at 406 and 446 nm, respectively. |
