摘要：
Two new 3d-4f heterometallic coordination polymers [Mn(0.5)Ln(INAIP)(2)(H2O)(2)]center dot 2H(2)O [ Ln = Eu (1), Gd (2)] have been prepared by hydrothermal reactions of the corresponding lanthanide salt with 5-(isonicotinamido) isophthalic acid (H(2)INAIP) in the presence of MnCO3 and NaOH. Both complexes have been characterized by single crystal X-ray diffraction analyses, elemental analyses, infrared absorption spectra, and thermogravimetric analyses. The results of structural analyses show that 1 and 2 are isostructural and feature non-interpenetrated 3D coordination framework containing 2D (4,4) lanthanide-carboxylate layers. They have the same 3D structure with trinodal (3,3,4)-connected new topology net with Point (Schlafli) symbol (8(3))(4)(8(4).10(2))(8(6))(2). In addition, photoluminescence and magnetic properties were also investigated. (C) 2011 Elsevier B. V. All rights reserved.

摘要：
A 3d-4f heterometallic coordination polymer, [Mn0.5Tb (INAIP)(2)(H2O)(2)]center dot 2H(2)O (1) has been prepared by hydrothermal reactions of the corresponding lanthanide salt with 5-(isonicotinamido)isophthalic acid (H(2)INAIP) in the presence of MnSO4 center dot H2O and NaOH. X-ray single-crystal structural analysis reveals that 1 features non-interpenetrated three-dimensional (3D) coordination framework containing two-dimensional (2D) (4, 4) Tb-carboxylate layers. In addition, 1 also displayed photoluminescent properties in the green range at room temperature.
摘要：
The novel complex [Zn_2(Mba)_3(Phen)_2EtOH)]·ClO_4 (Hmba=methoxybenzoic acid, Phen=1,10-phenanthroline, EtOH=ethanol) was synthesized by hydrothermal reactions, and its structure was determined by X-ray diffraction. The crystal belongs to the triclinic system, space group Pi with a=1.15362(1), b=1.3655(3), c=1.61451(1) nm, α=72.842(2), β=83.259(3), γ=72.083(2)°, V=2.3112(6) nm3, Z=2, μ(MoKα)=11.71 cm~(-1), F(000)=1120, R=0.0552 and wR=0.1157 (I > 2σ(I)). The two centric zinc(Ⅱ) ions in the complex locate in a distorted octahedral coordination geometry and a distorted trigonal bipyramid coordination geometry, respectively. Two bridging bidentate carboxyl groups and a μ_2-O carboxyl group from three methoxybenzoic acids act as the bridge to link two Zn(Ⅱ) ions. The asymmetric units are connected by π-π packing interactions between aromatic rings to form a three-dimensional supramolecular network. The experimental results show a good fluorescence property for the complex.

A new 3d-4f coordination polymer {[CuTb 2(INAIP) 3(HCOO)(H 2O) 3] · 3H 2O} n (1) was obtained by solvothermal assembly of CuCl 2·H 2O and Tb(NO 3) 3·6H 2O with the H 2INAIP (5-(isonicotinamido)isophthalic acid) ligand. Complex l crystallizes in triclinic, space group P1̄ with a=1.088 79(16) nm, b = 1.518 5(2) nm, c = 1.565 3(2) nm, D=2.338 1(6) nm 3, Z=2, C 43H 37CuTb 2N 6O 23,M r=1387.17, D c=1.970 g·cm -3,μ=3.538 mm -1, F(000)=1360,R int=0.021 2, R=0.058 9, wR =0.129 2. Single-crystal X-ray diffraction analysis revealed that each INAIP 2- ligand uses its two carboxyl groups to connect two or three Tb(III) ions into 2D lanthanide bi-layer structure. Then the 2D layers are further connected by pyridyl groups to give a three-dimensional (3D) pillared-layer structure. In addition, the luminescent property of complex 1 has been investigated at room temperature, and showed the obviously green photoluminescence in it. CCDC: 881422.

A cobalt coordination polymers [Co(dib)(SO 4) (1) was obtained by solvothermal assembly of CoSO 4·7H 2O with sodium formate in the presence of N-donor ligands, namely 1,4-di(1-imidazolyl) benzene (dib). Compound 1 crystallizes in monoclinic system, space group C2/ c with a=1.972 26(7) nm, b=0.977 0(3) nm, c=1.1839 6(4) nm, β=96.479(2)°, V=2.266 8(13) nm 3, Z=4, C 24H 20N 8CoO 4S, M r=575.47, D c=1.686 g·cm -3, μ=0.903 mm -1, F(000)=1 180, R int=0.018 3, R=0.024 6, wR=0.072 6. Single-crystal X-ray diffraction analysis revealed that each dib ligand in turn uses its two imidzole groups to connect two metal centers, then the two-dimensional (2D) layer is formed. On the other hand, the 2D layers are further connected by sulfate to give a three-dimensional (3D) pcu topologic structure. In addition, the magnetic property of complex 1 has been investigated in the temperature range of 1.8~300 K, and the results show the weak antiferromagnetic interactions between Co(II) ions bridged by sulfate.

摘要：
A complex [Cu(2,2'-bipy)( BAA)][Cu(2,2'-bipy)( BAA)(H2O)](2)center dot(H2O)(3) (BAA=benzilic acid anion, 2,2'-bipy=2,2'-bipyridine) has been synthesized. Crystal data for this complex are as follows: triclinic, space group P1, a=1.121 7(5) nm, b=1.360 2(6) nm, c=2.335 2(10) nm, alpha=99.260(6)degrees, beta=101.223(8)degrees, gamma=94.805(8)degrees, V=3.425(3) nm(3), D-c=1.385 g.cm(-3), Z=6, mu(Mo K alpha)=0.992 mm(-1), F(000)=1 474, final discrepancy factors R-1=0.056 1, wR(2)=0.112 8. There are three mononuclear copper(II) complexes in one asymmetric unit of the compound, where the three central Cu(II) ions are not all of the same coordination number. Cu(1) ion is tetra-coordinated, while Cu(2) ion and Cu(3) ion are both penta-coordinated. The cyclic voltammetric behavior and fluorescent property of the title compound were investigated. The results show that the electron transfer in the electrode reaction of the title complex is irreversible, and two electrons are involved in the oxidation of the title complex. When the exciting radiation setting at 478 nm, the title complex can give off fluorescent emission. CCDC: 788067.
