Crystal data for 1 are: monoclinic, space group C2/c, a = 14.4781(5) angstrom, b = 16.2221(7) angstrom, c = 21.3617(9) angstrom, and Z = 4. For 2: monoclinic, space group C2/c, a = 14.554(6) angstrom, b = 15.239(6) angstrom, c = 21.754(9) angstrom, and Z = 4. For 3: monoclinic, space group C2/c, a = 14.5285(16) angstrom, b = 15.3234(16) angstrom, c = 21.154(2) angstrom, and Z = 4. For 4: triclinic, space group P-1, a = 12.132(5) angstrom, b = 12.536(5) angstrom, c = 17.840(10) angstrom, and Z = 2. For 5: triclinic, space group P-1, a = 9.993(10) angstrom, b = 13.950(13) angstrom, c = 15.511(15) angstrom, and Z = 2. For 6: monoclinic, space group Pc, a = 12.402(7) angstrom, b = 12.919(8) angstrom, c = 7.893(5) angstrom, and Z = 2. In complexes 1-5, Co(II) or Mn(II) ions are coordinated by six N atoms from two terpyridine moieties. In complex 6 the Mn(II) atom coordinates only one terpyridine ligand. All these complexes are linked by hydrogen bonds and face-to-face pi-pi interactions into three-dimensional networks. In complexes 4-6 the available solvent areas imply their potential applications in gas adsorption or catalysis.

摘要:
Two complexes [Ag(bpy)(H2O)](Hbac) (1) and [Ag-2(bpy)(2)(H2O)(2)](pdc)(H2O)(5) (2) (H(2)bac = benzilic acid, bpy = 4,4 '-bypyridine, H(2)pdc = 2,6-pyridinedicarboxylic acid) have been synthesized and characterized by IR, element analysis, X-ray-single crystal diffraction and TGA. Crystal data for 1: Monoclinic, space group C2/c, alpha = 18.8192(5) a, b = 12.7131(5) a, c = 17.8373(8) a, beta = 95.745(4), V = 4246.1(3) a(3) and Z = 8; 2: Triclinic, space group, P-1, alpha = 8.132(5) a, b = 10.485(6) a, c = 18.026(10) a, alpha = 96.194(10), beta = 91.047(11), gamma = 105.866(10), V = 1468.0(15) a(3) and Z = 2. In complex 1, Ag(I) is coordinated by two discrete 4,4'-bpy ligands and one water molecule and Hbac(-) behaves as a counterpart anion. In the crystal, a 3D network was formed by hydrogen bonds and pi pi face-to-face interactions. In complex 2, Ag(I) is also coordinated by two discrete 4,4'-bpy ligands and one water molecule and pdc(2-) behaves as a counterpart anion, too. In the crystal, a similar 3D network was formed by hydrogen bonds and pi pi face-to-face interactions as well as that of complex 1. The luminescence properties of 1 and 2 have been investigated.
摘要:
A complex [Ni(meophtpy)(2)](ClO4)(2)center dot 2H(2)O (1) (meophtpy = 4'-(4-methoxyphenyl)-2,2':6',2 ''-terpyridine) has been synthesized and characterized by IR, element analysis, TGA and single crystal X-ray diffraction. The complex crystallizes in Tetragonal system with space group I4(1)/a, a = 24.470(4), b = 24.470(4), c = 13.845(5)angstrom, V = 8290.12 angstrom(3), Dc = 1.558 g/cm(3), Z = 8, F(000) = 4016, final GOF = 1.021, R-1 = 0.0619, and wR(2) = 0.1261 for 3616 observed reflections with I > 2 sigma(I). The crystal structure analysis shows that a three dimensional network overlapped with terpyridine motifs was formed by hydrogen bonds and pi-pi interactions which are seldom found in terpyridine complexes. Themagnetic property of 1 has also been investigated.

摘要:
The bifunctional pyridine-2,3-dicarboxylic acid (H(2)pdc) ligand has one N atom and four O atoms, which could bind more than one Ag-I centre with diverse binding modes. A novel infinite one-dimensional Ag-I coordination polymer, namely catena-poly[[silver(I)-(mu(2)-pyridine-2,3-dicarboxylato-kappa N-2:O-3)-silver(I)tris(mu(2)-5-methyl-1,3,4-thiodiazol-2-amine-kappa(2) N:N')] monohydrate ethanol monosolvate], {[Ag-2(C7H3NO4)(C3H5N3S)(3)]center dot H2O center dot C2H5OH}(n), has been synthesized using H(2)pdc and 5-methyl-1,3,4-thiadiazol-2-amine (tda), and characterized by single-crystal X-ray diffraction. One Ag-I atom is located in a four-coordinated AgN4 tetrahedral geometry and the other Ag-I atom is in a tetrahedral AgN3O geometry. A dinuclear Ag-I cluster formed by three tda ligands with a paddelwheel configuration is bridged by the dianionic pdc(2-) ligand into a one-dimensional coordination polymer. Interchain N-H center dot center dot center dot O hydrogen bonds extend the one-dimensional chains into an undulating two-dimensional sheet. The sheets are further packed into a three-dimensional supramolecular framework by interchain N-H center dot center dot center dot O hydrogen bonds.
摘要:
Five coordination complexes [Fe(ftpy)(2)] (ClO4)(2) center dot (H2O)(2) (1), [Cu(ftpy)(NO3)(H2O)](NO3) (2), [Cu(ftpy)(2)](2) (ClO4)(4) center dot (C2H5OH) (3), [Zn(ftpy)(2)] center dot (ClO4)(2) center dot (H2O)(1.5) (4) and [Cd(ftpy)(2)](2) (ClO4)(4) center dot (C2H5OH) (5) (ftpy= 4'-(furan-2-yl)-2,2':6', 2 ''-terpyridine) have been synthesized and characterized by IR, elemental analysis and single-crystal X-ray diffraction. With the exception of 4, all complexes adopt normal homoleptic [M(ftpy)2](2+) motifs. In the crystal, both hydrogen bonds and face-to-face interactions between furyl and pyridyl rings facilitate the construction of three-dimensional networks. The DNA-binding activities of the five complexes have been investigated by fluorescence emission titration at room temperature suggesting an intercalative mode for 1-3 with a relative order, 3 > 2 > 1, and a combined static and dynamic mode for 4 and 5.

摘要:
Four homoleptic copper(II) complexes, [Cu(Meophtpy)2](ClO4)2 (Meophtpy = 4′-(4-methoxylphenyl)- 2,2′:6′,2″-terpyridine) (I), [Cu(Meophtpy)2](ClO4)2 · 2H2O (II), [Cu2(m-Clphtpy)4](ClO4)4 (m-ClPhtpy = 4′-(3-chlorophenyl)-2,2′:6′,2″-terpyridine) (III), and [Cu2(m-ClPhtpy)4](ClO4)4 (IV) have been synthesized by hydrothermal methods and characterized by IR, elemental analysis and single crystal X-ray diffraction (CIF files CCDC nos. 963375 (I), 885457 (II), 963377 (III), and 963376 (IV)). Complex II is a polymorph of I and complex IV is a polymorph of III. All these complexes are obtained with 95% ethanol solution or 50% ethanol solution and the solvent control on the crystallization are obviously found. In all complexes, the face-to-face interactions between pyridyl rings or phenyl rings facilitate the construction of 3D network in the crystal in addition to hydrogen bonds. The fluorescence properties of these complexes have been investigated.
