A novel coordination ploymer [Cd(HO-BDC)(phen)·H2O]n (where HO-BDC is 5-Hydroxyisophthalic acid and phen is 1,10-phenanthroline) has been synthesized and characterized by elemental analysis, IR spectra and single-crystal X-ray diffraction. The crystal belongs to monoclinic, space group P2/c, with a=0.876 4(2) nm, b=1.233 0(3) nm, c=1.761 2(4) nm, β=109.152(9)°, V=1.797 8(7) nm3, Z=4, Mr=490.73, Dc=1.813 g·cm-3, F(000)=976, μ=1.258 mm-1, the final R=0.043 8 and wR=0.098 9 for 2 880 observed reflections with I>2σ(I). The structural analysis shows that the complex has a one-dimensional chain structure. CCDC: 609770.
A novel heterometallic complex [Na2Cu2Gd2(pdc)4(H2O)14·2H2O] (H3pdc = 1H- pyrazole-3,5-dicarboxylic acid) has been synthesized and characterized by IR spectra, elemental analysis, and single-crystal X-ray analysis. The crystal belongs to the monoclinic system, space group P21/c with a = 7.9521(18), b = 12.251(3), c = 22.293(5) , β = 110.173(5)o, V = 2038.5(8) 3, Mr = 1388.13, Z = 2, F(000) = 1352, Dc = 2.261 g/cm3, μ = 4.380 mm-1, the final R = 0.0409 and wR = 0.0622 for 2453 observed reflections with I > 2σ(I). The structural analysis shows that the NaI, CuII and GdII ions are linked together by two kinds of bridging ligands (pdc3- and H2O) to form a main moiety [Na2Cu2Gd2(pdc)4(H2O)14], which can be regarded as a centrosymmetric dimmer of [NaCuGd(pdc)2(H2O)7]. Many hydrogen bonds exist in the complex to build a 3D supramolecular framework.
A novel coordination polymer [{Cd(hmbdc)(H2O)3}·2H2O]n (hmbdc = 5-hydroxy- isophthalic acid) has been synthesized and characterized by elemental analysis, IR spectra and single-crystal X-ray diffraction. The crystal belongs to monoclinic, space group P21/c, with a = 9.599(3), b = 18.699(5), c = 7.557(2) , β = 108.198(4)°, V = 1288.6(6) 3, Z = 4, Mr = 382.60, Dc = 1.972 g/cm3, F(000) = 760, μ = 1.740, the final R = 0.0555 and wR = 0.0995 for 1732 observed reflections with I > 2σ(I). The structural analysis shows that the intermolecular hydrogen bonds and π-π interactions result in a three-dimensional supramolecular framework.
The title complex, [Y(sip)(H2O)4]n (sip = 5-sulfoisophthalate), has been synthesized and characterized by elemental analysis, IR spectra and single-crystal X-ray analysis. The crystal belongs to the orthorhombic system, space group Pna21, a = 7.235(4), b = 16.456(5), c = 10.316(3) , V = 1228.2(9) 3, Z = 4, Mr = 404.14, Dc = 2.186 g/cm3, F(000) = 808, μ = 4.979 mm-1, the final R = 0.0474 and wR = 0.1125 for 2122 observed reflections with I ( 2σ(I). The structural analysis shows that the intermolecular hydrogen bonds and (-( interactions result in a three-dimensional supramo- lecular structure. The complex shows intense luminescence in solid state at room temperature.
