| Popis: | Three novel coordination polymers [Zn(ctpy)(Cl)] n ·(H 2 O) n ( 1 ), [Zn 2 (ctpy) 2 (tp)] n ( 2 ) and [Cu 2 (ctpy) 2 (tp)] n ( 3 ), Hctpy = 4′-carboxy-4,2′:6′,4″-tpyridine, H 2 tp = terephthalic acid, have been hydrothermally synthesized and characterized by elemental analysis, IR, single crystal X-ray diffraction. Compounds 1 and 3 show the utp and ins topologies with 2- and 3-fold interpenetrating structures, while compound 2 is a non-interpenetrating (4,4)-connected 2D layer with one-dimension channels along b axis and further assembles into a 3D supramolecular structure by π … π stacking interactions. The structural diversity of compounds 1 – 2 may illustrate the marked effect of the pH of the reaction system. The diversity structures of the compounds 2 and 3 may illustrate the marked effect of metal ion. Furthermore thermal stabilities and photoluminescent properties were also studied. |
