Four distinct Zn-II coordination polymers [Zn(L-5)Cl-2](n) (1), [Zn(L-5)I-2](n) (2), {[Zn(L-5)(N-3)(2)](H2O)(2)}(n) (3), and {[Zn(L-5)(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 (L-5) with different Zn-II 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 L-5 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.
