Four polymeric frameworks, [Zn(cptpy)2(Hcptpy) 2]·2H2O (1), [Zn(cptpy)Cl]n (2), [Zn4(cptpy)2(3-btc)2]n· nH2O (3) and [Zn2(cptpy)(2-btc)]n (4), (Hcptpy = 4′-(4-carboxyphenyl)-3,2′:6′,3″-terpyridine, H 3(3-btc) = 1,3,5-benzenetricarboxylic acid, H3(2-btc) = 1,2,4-benzenetricarboxylic acid) have been hydrothermally synthesized and characterized by elemental analysis, IR spectroscopy and single crystal X-ray diffraction analyses. Compound 1 has a mononuclear structure, while 2 shows a one-dimensional ladder chain containing 28 member rings with (cptpy)- anions as bridges. For compounds 1 and 2, weak hydrogen bonding and intra- and/or inter-molecular π?π stacking interactions link the mononuclear or infinite chain structures into high-dimensional supramolecular structures. Compound 3 reveals a (4,4,4)-connected three-dimensional (3D) framework. Compound 4 is a three dimensional network structure comprised of new tetranuclear zinc clusters, exhibiting a {4·6·8}{4 2·6·83}{42·6 2·82}{43·62· 85} topological structure. In addition, the thermal stabilities and photoluminescence properties of 1-4 were also studied.
