摘要:Five coordination polymers based on 5,5′-(2,3,6,7-tetramethoxyanthracene-9,10-diyl)diisophthalic acid (H4L~(OMe)): [Mn4(L~(OMe))(OAc)2(μ3-OH)2(NMP)4(H2O)2]·2H2O (1), [Ni2(L~(OMe))_+(0.5)(H2L~(OMe))0.5(μ3-OH)(H2O)3]·6H2O (2), [Cd2(L~(OMe))(H2O)2(NMP)]·2DMF·NMP·H2O (3), [Co2(L~(OMe))(H2O)2]·2NMP·DMA·2H2O (4), [Zn2(L~(OMe))(H2O)2]·2NMP·2H2O·DOE (5) (NMP = N-methylpyrrolidone, DMF = N,N′-dimethylformamide, DMA = N,N′-dimethylacetamide, DOE = 1,4-dioxane) were prepared by solvothermal methods and characterized by elemental analysis (EA), single-crystal X-ray crystallography, powder X-ray diffraction (PXRD), infrared spectroscopy (IR), and thermogravimetric analyses (TGA). X-ray crystallography analysis shows that complex 1 bears a two-dimensional (2D) (4,4) network based on tetranuclear secondary building units, which are further assembled into a three-dimensional supramolecular structure via π···π stacking interaction; complex 2 displays a 3D framework with fsc topology based on 2D 4~4-sql layers and tetranuclear SBUs; complex 3 reveals a 3D PtS network via the L~(OMe) bridging dimetal {Cd2O_(11)} units; complexes 4 and 5 possess 3D open frameworks with a rarely reported 3-nodal (4,4,4)-connected nou network. Moreover, magnetic susceptibility measurement of complexes 1 and 2 confirm the presence of magnetic exchange coupling among the metal ions of tetranuclear clusters, and fluorescent spectra of complexes 1, 3 and 5 show emission signals in the blue region.
