By reacting an asymmetry semi-rigid V-shaped linker H3L (H3L = 3-(3-carboxyphenoxy) phthalic acid) and Zn(NO3)(2)center dot 6H(2)O under different N-donor ligands in different solvents, four new Zn-based coordination polymers, [Zn(HL)(2,2'-bpy)(H2O)](x), (1), [Zn(HL)(4,4'-bpy)](n)center dot n(DMA) (2), [Zn-3(O-2(phen)(3)(H2O)1,1- n(H2O) (3) and [Zn(HL)(plien)(1-120)]2 (4) (2,2'-bpy = 2,2'-bipyridine; 4,4'-bpy = 4,4'-bipyridine; phen = 1,10-phenanthroline; DMA = N,N-dimethylacetamide) have been obtained. All of these compounds have been clearly identified by single crystal X-ray diffraction analysis. Compound 1 exhibits onedimensional (1D) chain structure constructed from uninuclear Zn(II) motif, which further extends into 2D supramolecular architecture via intermolecular pi-pi interactions and hydrogen bonds. Structural analysis reveals that the structure of 2 and 3 can be described as a 2D hcb topology network with the point symbol of {63). Compound 4 shows a OD binuclear motif while its 3D packing network has a large potential solvent voids. The results of this research demonstrate that the solvent and the secondary ligands could co-regulate different structural coordination polymers with interesting properties. In addition, the thermal stabilities and solid-state luminescence properties of compounds 1-4 have also been investigated.
