Metal-organic frameworks(MOFs), consisting of metal, anion and organic ligands, have attracted much attention. The structure of MOFs is affected by various factors. To explore the effects of metal ions, we synthesized six complexes, namely {[Me_2NH_2][Zn_4(H_2L)(L)]·2 H_2O·2 DMF}_n(1), {[Me_2NH_2]_2[Cd_2(L)]·2H_2O}_n(2), {[Me_2NH_2]_2[Ca_3(L)(μ-OH)_2(DMF)_2]·2H_2O}_n(3) and {[Me_2NH_2]_2[M_2(L)(μ-OH)]· H_2O·2DMF}_n(M = Co, 4; Ni, 5; Mn, 6), from a C_(2v)-based hexacarboxylate ligand([1,1';4',1']terphenyl-3,5,2',5',3',5'-hexacarboxylic acid(H_6L)) using metal-induced strategy. These MOFs were thoroughly characterized by single-crystal and X-ray diffraction, elemental analysis, Fourier-transform infrared spectra(FTIR) and photoluminescence. 相似文献
