Four distinct ZnII coordination polymers [Zn(L5)Cl2]n (1), [Zn(L5)I2]n (2), {[Zn(L5)(N3)2](H2O)2}n (3), and {[Zn(L5)2(H2O)](ClO4)2(CH3OH)}n (4) were prepared by assembling a multidentate tripyridyltriazole building block 3-(2-pyridyl)-4-(4-pyridyl)-5-(3-pyridyl)-1,2,4-triazole (L5) with different ZnII salts. Compounds 1, 2 and 4 display distinguishing 1D chain-like coordination patterns whereas 3 reveals a 2D uninodal four-connected network, which can be well regulated by different counter-ions. Further, the building tecton L5 exhibits multiple conformations in these structures. The structural diversity reveals that the synergistic modulation of counter-ions and the adaptable conformations of the organic linker play a critical role in the structural construction. Solid-state properties including thermal stability and fluorescence were investigated as well.

Two coordination polymers, [Co(µ4-L)(H2O)2]n (1) and [Ni(µ-L)(H2O)4]n (2), were solvothermally assembled from the corresponding metal(II) chlorides and biphenyl-4,4-dioxydiacetic acid (H2L) as a flexible dicarboxylate linker. The cobalt(II) compound 1 featured a layer-pillared 3D metal-organic network with a cds topology, while the nickel(II) derivative 2 represented a linear chain 1D coordination polymer with a 2C1 topology. The µ4− and µ-L2− linkers exhibited different denticity and coordination modes in the synthesized compounds, thus contributing to their structural diversity. The dimensionality of 1 and 2 had an influence on their thermal stability and decomposition processes, which were investigated in detail by TG-DSC and TG-FTIR methods. Thermal decomposition products of coordination polymers were also analyzed by PXRD, confirming the formation of Co3O4/CoO and NiO as final materials. The obtained compounds broaden a family of coordination polymers assembled from flexible dicarboxylate linkers.
