| Abstract: Two 2D coordination polymers, namely {[Cu3(μ4-dpna)2(2,2'-bipy)2]·4H2O}n (1) and {[Zn3(μ4-dpna)2(2,2'-bipy)2(H2O)2]·6H2O}n (2) as well as two 1D coordination polymers, namely {[M2(μ4-deta)(phen)2(H2O)]·3H2O}n (M=Mn (3), Zn (4)) have been constructed hydrothermally using H3dpna (H3dpna=5-(3',4'-dicarboxylphenoxy)nicotic acid) or H4deta (H4deta=2,3,2',3'-diphenyl ether tetracarboxylic acid) as a principal building block, 2,2'-bipy (2,2'-bipy=2,2'-bipyridine) or phen (phen=1,10-phenanthroline) as a auxiliary ligand, and copper, zinc or manganese chlorides. The products were isolated as stable crystalline solids and were characterized by IR spectra, elemental analyses, thermogravimetric analyses (TGA), and single-crystal X-ray diffraction analyses. Single-crystal X-ray diffraction analyses revealed that compounds 1 and 2 crystallize in the monoclinic system, space groups P21/c or C2/c. Compounds 1 and 2 disclose two different 2D sheet structures. The structural difference of compounds 1 and 2 is driven by the Cu(Ⅱ)/Zn(Ⅱ) nodes. Compounds 3 and 4 are isostructural and crystallize in the monoclinic system, space group P21/n. Both compounds show a 1D chain structure. The luminescent and photocatalytic properties of the compounds were investigated, showing that compounds 2 and 4 can effectively degrade methylene blue as a model organic dye pollutant. |
