The supramolecular terbium complex, {[Tb(SIP)(H2O)5]2(bpy)3(H2O)}n (NaH2SIP = 5-sulfoisophthalic acid monosodium salt and bpy = 4,4'-bipyridyl), has been synthesized by the hydrothermal reaction of Tb4O7 with NaH2SIP and bpy at 165 ℃, and characterized by single-crystal X-ray diffraction, elemental analysis, IR spectrum, powder X-ray diffraction and photoluminescence spectrum. It crystallizes in a monoclinic system, space group C2/c, with a = 30.6840(1), b = 10.9206(2), c = 17.4967(3) A, β= 111.931(1)°, V = 5438.65(14) A^3, Z = 4, C46H52N6O25S2Tb2, Mr = 1470.90, Dc = 1.796 g/cm^3, p = 2.747 mm^-1, F(000) = 2928, the final R = 0.0654 and wR = 0.1322 for 3806 observed reflections with I 〉 2σ(I). In the neutral [Tb(SIP)(H2O)5]2 motif, the Tb(III) ions are linked by the SIP ligands to form a one-dimensional zigzag chain propagating along the c axis. The zigzag chains are linked together by hydrogen bonds and π-π stacking interactions to form a two-dimensional supramolecular framework. The uncoordinated bpy molecules act as pillars to extend the two-dimensional sheets into a distinctive pillared three-dimensional supramolecular structure through O-H...N hydrogen bonds. The photoluminescence of the complex was investigated at room temperature in the solid state.  相似文献

O-(p-tolyl)dithiophosphato nickel complex [Ni(S2P{O}OC6HaCH3-p)(dppv)] has been synthesized by the treatment of (dppv)NiCl2 (dppv = Ph2PCH=CHPPh2) with (p-CH3C6HaO)2P{S}SH'Et2NH in THF. The new complex was fully characterized by elemental analysis, IR, 1H NMR, 31p NMR spectroscopies and thermo-gravimetric analysis. The molecular structure of the complex was established by X-ray crystallography. The crystal crystallizes in monoclinic, space group P21/c with a = 9.2739(5), b = 17.8803(8), c = 20.1879(12) A, fl = 93.269(5), V = 3342.1(3) A3, Z = 4, C33H29NiO2P3S2, Mr = 673.30, Dc = 1.338 g/cm3, F(000) = 1392 and #(MoKa) = 0.877 rnm-l. The final R = 0.0578 and wR = 0.1045 for 4138 observed reflections with 1 〉 20(/) and R = 0.1050 and wR = 0.1204 for all data. The Ni centre atom adopts a NiP2S2 square-planar geometry with two phosphorus atoms from the dppv ligand and two sulfur atoms from the O-(p-tolyl)dithiophosphate ligand. The most interesting structural feature of the title complex resides in its 1D helical chain structure constructing via intermolecular C-H'"O secondary interactions along the b-axis. The adjacent helical chains running in opposite directions are connected into a 1D double-stranded helical chain and further linked into a 2D supramolecular network by weak C-H.--C interaction.  相似文献

The title compounds have been respectively synthesized by solution process and solvothermal reaction, and their crystal structures were determined by X-ray diffraction method. For (CH3CH2CH2CH2NH3)6(BiI6)(I)2I3 1, it crystallizes in tficlinic, space group P1^- with Mr = 2049.76, a = 8.5719(1), b = 11.7461(3), c = 15.700(1)A, V = 1451.4(1)A^3, Z = 1, Dc = 2.345 g/cm^3, F(000) = 924, μ(MoKα) = 8.907 mm^-1, T = 293(2) K, the final R = 0.0655 and wR = 0.0804 for 2399 observed reflections with I 〉 2σ(I). For (NH3CH2CH2NH3)2Bi2I10 2, it crystallizes in monoclinic, space group P21/n with Mr= 1811.20, a = 8.434(4), b = 13.862(6), c = 13.362(6)A, V = 1499.9(12)A^3, Z = 2, Dc = 4.010 g/cm^3, F(000) = 1536,μ(MoKα) = 22.007 mm^-1, T = 293(2) K, the final R = 0.0584 and wR = 0.1451 for 1798 observed reflections with I 〉 2σ(I). The structures of 1 and 2 contain halobismuthate monomer and dimers, respectively. It is noteworthy that the dimers and their organic counters in 2 connect each other by N…I hydrogen bonds to form a layered structure, and the electrostatic interactions and crystal packing forces between layers give rise to the packing of the crystal. The optical absorption spectra of 1 and 2 reveal the appearance of sharp optical gaps of 2.13 and 2.01 eV, respectively.  相似文献

It crystallizes in monoclinic, space group P211n with a = 11.3533(8), b = 15.4939(11), c = 20.5189(14) A, β = 98.577(2)°, V = 3569.0(4) A3, Z = 2, C56H82Cl4Cu2In4O8P2S4, Mr = 1801.56, Dc = 1.676 g/cm3,μ(MoKa) = 2.213 mm^-1, F(000) = 1796, S = 0.985, the final R = 0.0559 and wR = 0.1099 for 8878 observed reflections with I 〉 2σ(I) and 367 variables. Complex 1 consists of two CuPPh3 fragments which symmetrically side-attach to the tetranuclear core of [InaCl4(OMe)2(μ-OMe)a(μ- OMe)2(μ-SPrn)4] by coordinating with sulfur atoms of propane-thio moieties. The average In-Ot (terminal), In-μ-O and In-μ3-O bond distances are 2.305(4), 2.144(4) and 2.294(4) A, respectively.  相似文献

A new iodiplumbate polymer [(AOD)(Pb216)]n 1 (AOD = O-protonated 4-azonia-7- oxaspiro(4,5) decane quaternary ammonium) was synthesized by self-assembly reaction of AOD-I, Pb(NO3)2 and NaI, and structurally determined. Compound 1 crystallizes in the hexagonal system, space group P3, with a = 18.2704(8), c = 8.1663(6) A, V= 2360.8(2) A3, Z = 3, De = 2.783 g/cm^3, F(000) = 1686, C8H17I6NOPb2, Mr = 1319.03, μ(MoKa) = 16.562 mm^-1, the final R = 0.0535 and wR = 0.1793 for 4943 observed reflections with I 〉 2σ(I). In compound 1, three independent (PbEI6)^2-n infinite chains in each unit cell shape the sketch of compound 1 under the template of AOD-H^2+ cation. Each (PbaI6)^2-n chain generates from the face-sharing of distorted PbI6 octahedra. (PbEI6)^2-n polyanions interact with AOD-H^2+ cations by electrostatic interaction in the crystal to feature a so-called hybrid structure. Compound 1 was further characterized with IR, elemental analysis, fluorescence spectrum and thermal analysis. Based on the crystal structure data, DFT calculation was carried out to reveal the electronic structure of compound 1.  相似文献

1 INTRODUCTION The interest in the complexes of transition metals with ligands ketoxime[1, 2] as potential models for metal binding sites in ferroverdin[3, 4] has prompted the investigation on the structures and the overall coordination geometry of the metal centers in these complexes. Oxime derivatives are interesting ligands since the ketoximes are found to chelate transition metals through the N (oxime) and O (ketone) atoms[5, 6]. However, monodentate coordination via only one O or …  相似文献

The complex [Cd(H2mbdpz)(N3)2]n 1 (H2mbdpz = 4,4′-methylenebis(3,5-dimethylpyrazole)) has been hydrothermally synthesized and characterized by single-crystal X-ray diffraction analysis. It crystallizes in the monoclinic system, space groups C2/c with a = 22.154(5), b = 7.4835(15), c = 21.044(8)A^°,β= 115.51(3)°, V= 3148.7(17)A^°3, Z= 8, C11H16CdN10, Mr = 400.75, Dc = 1.691 g/cm^3,μ = 1.401 mm^-1, F(000) = 1599, T= 293(2) K, the final R = 0.0228 and wR = 0.0581 for 3604 observed reflections with I 〉 2σ(I). The structural determination revealed that the coordination environment of Cd(Ⅱ) atom is a distorted octahedron consisting of two nitrogen donors of two H2mbdpz ligands and four nitrogen donors from four azide ligands. The azide moieties act as bridges in two modes: end-on (μ1,1-) and end-to-end (μ1,3-), and H2mbdpz also serves as a bridge with a bis-monodentate coordination. Both bridging ligands link the Cd(Ⅱ) atoms to form a distorted two-dimensional (6,3) layer.  相似文献
