Four Zn(II) coordination polymers, namely {[Zn(chedc)(4,4′-Hbpt)]}n (1), {[Zn3(chadc)2(4,4′-Hbpt)2(4,4′-bpt)2]·3H2O}n (2), {[Zn2(chadc)2(3,3′-Hbpt)]}n (3) and {[Zn2(chedc)2(3,3′-Hbpt)]·H2O}n (4) (chadc = cis-1,2-cyclohexanedicarboxylate anion, chedc = cis-4-cyclohexene-1,2-dicarboxylate anion, 4,4′-Hbpt = 1H-3,5-bis(4-pyridyl)-1,2,4-triazole, 3,3′-Hbpt = 1H-3,5-bis(3-pyridyl)-1,2,4-triazole) have been produced by the reaction of two positional isomeric dipyridyl bridging ligands and two dicarboxylate anions with Zn(II) salts under hydrothermal conditions. Structural analysis reveals that 1 exhibits a double-chain and 2 exhibits a 3D network with a (62.10)2(64.102) topology, whilst 3 and 4 show similar layer structures. The luminescent properties of these complexes have been briefly investigated.
Graphical abstractIn this paper, four mixed-ligand Zn(II) coordination polymer have been designed and synthesized under hydrothermal conditions. Compounds 1–4 exhibit a double-chain, a 3D network with (62.10)2(64.102) topology and two polymeric coordination layer structures, respectively. The luminescent properties of the complexes have also been investigated in the solid state at room temperature.Figure optionsDownload full-size imageDownload as PowerPoint slideHighlights► Four Zn(II) coordination polymers with new mixed-ligand system have been synthesized. ► Bpt isomers and dicarboxylate ligands displays diverse coordination modes. ► Their photoluminescent properties were also investigated.
