摘要：

Two novel coordination polymers, [Zn-4(hfpd)(2)(phen)(4)(H2O)(4)](n) (1), {[Cd-2(hfpd)(bpy)(H2O)]center dot H2O}(n) (2) (phen = 1,10-phenanthroline, bpy = 4,4'-bipyridine, H(4)hfpd = 4,4'-(hexafluoroisopropylidene) diphthalic acid), were synthesized and characterized by elemental analyses, FT-IR spectra, single-crystal X-ray diffraction analyses, TGA, powder XRD and fluorescent measurements. Compound 1 shows a 2D network structure built from tetranuclear zinc unit interconnected by (hfpd)(4-) ligands. The adjacent networks are further packed into 3D supramolecular structure through pi center dot center dot center dot pi interactions. 2 possess an unprecedented 3D structure containing 26-number circles and 1D parallelogram channels. Especially the (hfpd)(4-) ligands in 1-2 adopt three different conformations and coordination modes. In addition, the thermal stability and photoluminescence properties of 1-2 were also studied.
