| Abstract: | Three new supramolecular compounds were synthesized and characterized with the formula of Zn4(picO)4(phen)4]·11.25H2O ( 1 ), Zn4(picO)4(2,2′‐bpy)4(H2O)4]·12H2O ( 2 ), and Zn3(picO)3(bpe)5(H2O)3]n·8.5nH2O ( 3 ) (H2picO = 6‐hydroxypicolinic acid; phen = 1,10‐phenanthroline; 2,2′‐bpy = 2,2′‐bipyridine; bpe = 1,2‐bis(4‐pyridyl)ethane). For complexes 1 and 2 , picO ligands adopt tridentate, tetradentate and bidentate coordination modes to link zinc(II) ions into dimers, which are extended into 3D supramolecular structures through hydrogen bonds. Water chains with cyclic page‐like octamer and boat‐like heptamer water clusters are included, respectively. Complex 3 is of a 2D brick‐wall structure. Triple interpenetration occurs, and there are still cyclic chair‐like octamer water clusters in the channels. The fluorescent properties of complexes 1‐3 have also been investigated. |
