摘　　要：Two 1D and one 3D coordination polymers,namely[Ni2(μ3-deta)(H2 biim)3(H2O)2]n(1),{[Zn2(μ4-deta)(Phen)2(H2O)]·H2O}n(2)and[Cd2(μ6-deta)(Phen)2(H2O)]n(3),have been constructed hydrothermally using H4deta(H4deta=2,3,3’,4’-diphenyl ether tetracarboxylic acid),H2 biim(H2 biim=2,2’-biimidazole),phen(phen=1,10-phenanthroline),and nickel,zinc or cadmium chlorides at 160℃.The products were isolated as stable crystalline solids and characterized by IR spectra,elemental analyses,thermogravimetric analyses(TGA)and single-crystal X-ray diffraction analyses.Single-crystal X-ray diffraction analyses revealed that three compounds crystallize in the triclinic system,space group■.Compounds 1 and 2 disclose a 1D chain structure.Compound 3 features a 3D framework.The structural diversity of compounds 1~3 is driven by the metal(Ⅱ)node and the type of supporting ligand.Magnetic studies for compound 1 demonstrate an antiferromagnetic coupling between the adjacent Ni(Ⅱ)centers.The luminescence behavior of compounds 2 and 3 was also investigated.
