The self-assembly of a flexible bipyridyl ligand 2,2?-bis(4-pyridylmethyle- neoxy)-1,1?-biphenylene (4,4?-bpp) with cobalt(II) center gave rise to a one-dimensional chain complex [Co(μ-4,4?-bpp)2(SCN)2?H2O]n 1 which ... The self-assembly of a flexible bipyridyl ligand 2,2?-bis(4-pyridylmethyle- neoxy)-1,1?-biphenylene (4,4?-bpp) with cobalt(II) center gave rise to a one-dimensional chain complex [Co(μ-4,4?-bpp)2(SCN)2?H2O]n 1 which has been characterized by single-crystal X-ray diffraction. The polymer crystallizes in monoclinic, space group C2/c with unit cell parameters: a = 13.1888(13), b = 24.230(2), c = 15.4218(17) ?, β = 93.291(6)o, V = 4920.1(8) ?3, Z = 4, C50H42CoN6O5S2, Mr = 929.95, Dc = 1.255 g/cm3, F(000) = 1932 and μ(MoKα) = 0.484 mm-1. The final R and wR are 0.0691 and 0.1670 for 3746 observed reflections with I > 2σ(I). 1 possesses an infinite 1-D polymeric chain structure consisting of the repeated basic square units Co2(μ-4,4?-bpp)2, where the Co(II) center acts as the joint of the square ring. The Co(II) center is coordinated in a slightly distorted octahedral geometry with four nitrogen atoms from four different 4,4?-bpp ligands in the equatorial plane and two trans thiocyanate ligands occupying the axial positions, preventing the formation of an extended framework. 展开更多

Each Co atom is octahedrally coordinated by three N atoms and three O atoms to form 2D 2 ∞ [Co(phen)(μ-L)3/3] polymeric layers. Furthermore, such 2D layers are stacked into 3D supramolecular frameworks via Van der Waals’ intermolecular forces, strong and weak hydrogen-bond interactions.

Polymer 1 consists of (Cd-Hiba)2 zigzag chains, which are further linked by hydrogen bonding to extend into a two-dimensional (2D) corrugated-shape sheet structure. The 2D structures are further connected into a 3D supramolecular edifice through hydrogen bonding. The polymer exhibits exceptional high thermal stability. The bulk purity of the materials of 1 was confirmed through the powder X-ray diffraction (PXRD) patterns. The luminescent property of polymer I has also been investigated. 展开更多

Two new cadmium(II)-thiocyanato coordination polymers with 4,4'-dimethyl-2,2'-bipyridine(4,4'-dm-2,2'-bpy) and 4,4'-dimethoxy-2,2'-bipyridine(4,4'-dmo-2,2'-bpy) as chelating ligands were synthesized and characterized by elemental analysis, IR and 1H NMR spectroscopy and X-ray crystallography. Thermal properties were also studied as well. These complexes have formed as [Cd(4,4'-dm-2,2'-bpy)(NCS)2]n(1) and [Cd(4,4'-dmo-2,2'-bpy)(NCS)2]n(2). The coordination numbers of CdII in 1 and 2 are six(Cd N4S2). Direction of bridging of thiocyanato anions in 1 and 2 created one- and two-dimensional coordination polymers, respectively. The supramolecular features in these complexes were guided and controlled by weak directional intermolecular interactions. 展开更多

A new complex with formula [Cd(3-pbpmb)2 I2]n 1(3-pbpmb = 1,4-bis(pyridine-3-ylmethoxy)benzene), has been solvothermally synthesized and characterized. The crystal belongs to monoclinic system, space group P21/n with a = 8.2905(17), b = 16.078(3), c = 13.213(3)A, β = 99.44(3)°, Mr = 950.86, V = 1737.3(6) A^3, Z = 2, Dc = 1.818 g/cm^3, F(000) = 924, m = 2.450 mm(-1), the final R = 0.0198 and w R = 0.0467 for 3053 observed reflections(I &gt; 2σ(I)). The Cd(Ⅱ) ion is coordinated by four N atoms of four 3-pbpmb ligands and two iodine ions to furnish a distorted octahedral coordination geometry. The Cd(Ⅱ) ion and its own symmetry-related ions are bridged by N atoms from two 3-pbpmb ligands to generate a "zigzag" 1-D chain coordination polymer. These 1D chains are further connected into a three-dimensional(3D) framework by C–H×××pinteractions and intermolecular C–H×××I hydrogen bond. Interestingly, 1 displays efficient sorption of molecular iodine gas(up to 111 wt%), but invalid sorption of molecular water gas. 展开更多

The crystal of the complex belongs to the triclinic system, space group P , with a=7.0737(9), b=8.7886(11), c=9.4561(12) , α=105.3580(10), β=94.981(2), γ=96.879(2)°, V=558.46(12) 3, Mr=714.97, Z=1, F(000)=346, Dc=2.126 g/cm3, μ=2.412 mm-1, T=296(2) K, S=1.057, R=0.0533 and wR=0.1480. According to the structural analysis, the Cd(Ⅱ) ion adopts a slightly distorted six-coordinated octahedral geometry. The Cd(Ⅱ) atoms are bridged by four Cl atoms along the a direction, forming infinite straight chains which are further constructed to generate 2D network layer structures through the μ4-N bpme ligand in the b direction, and such 2D network layer structures finally form a novel three-dimensional infinite supramolecular framework through weak π-π stacking between two network layers and hydrogen bonds. 展开更多

A novel two-dimensional lead(II) coordination polymer 1, [C11H7Cl2NO3Pb]n, has been prepared by solvothermal reaction of new bridging ligand(5-chloro-quinolin-8-yloxy)acetic acid(HL) with PbCl2, and its structure was characterized by IR, elemental analysis, TG-DTA and single-crystal X-ray diffraction analysis. The crystal is of monoclinic system, space group P21/c with a = 16.7603(7), b = 8.6907(4), c = 8.4745(3)A, β = 101.1110(11)°, C11H7Cl2NO3 Pb, Mr = 479.27, V = 1211.25(9)A3, Z = 4, Dc = 2.628 g/cm^3, F(000) = 880, μ = 14.367 mm^-1, R = 0.0173 and wR = 0.0508. The asymmetric unit contains one lead(II) cation, one(5-chloro-quinolin-8-yloxy)acetate(L) ligand and a chloride ion. The PbII center is hepta-coordinated in a distorted pentagonal bipyramidal geometry. The coordination sphere of the Pb atom is completed by two oxygen atoms and one nitrogen atom of the same L ligand, two bridging chloride ions and two bridging oxygen atoms of two adjacent L ligands. Two PbII centers are linked by the two L ligands to form a C2-symmetric dimer unit with a planar [Pb2O2] ring. Each dimer unit acts as a secondary building unit(SBU) and links adjacent four dimer units by the chloride atoms and oxygen atoms of carboxylate groups of L, forming a two-dimensional array. Such two-dimensional layers are packed through intermolecular C–H…Cl hydrogen bonds into a three-dimensional supramolecular structure. When the dimer unit is viewed as a 4-connected node, 1 is simplified as a 4-nodal 2-D network with square lattices of the diagonal lengths to be 6.079(1)A. The fluorescence emission peak of complex 1 appears near 407 nm. 展开更多

The crystal belongs to the monoclinic system, space group P21/c with a = 9.4564(10), b = 18.2679(19), c = 15.7284(12) A,β= 126.045(4)°, V= 2196.9(4)A^3, Z= 4, Dc = 1.618 g/cm^3, Mr = 535.02,μ = 1.141 mm^-1, F(000) = 1100, 2(MoKα) = 0.71073 A, the final R = 0.0429 and wR = 0.1044 for all observed reflections. In the structure, every two Cu(II) atoms are bridged by a bivalent 5-sulfosalicylic anion to form a 1D chain-like coordination polymer. Lattice waters between chains link them to form 2D layers which are further linked by C-H…O hydrogen bonds to form a three-dimensional supramolecular network. 展开更多

Crystal data for this complex are as follows: monoclinic, space group P2Jc, a = 7.7713(7), b = 27.478(3), c = 13.2621(13)/1,, fl = 100.6940(10), V= 2782.8(5) A3, Dc = 1.722 g/cm3, Z = 4, p = 1.61 mm-1, F(000) = 1472, the final R = 0.0363 and wR = 0.0933. In the crystal structure, the whole molecule consists of two cooper ions, two H2L, one 2,2"-bipy molecule and six water molecules. Each central copper ion is coordinated with three oxygen atoms from two H2L and one water molecule, two nitrogen atoms from one 2,2'-bipy molecule and two H2L, giving a distorted tetragonal pyramidal geometry. Thermal stability properties of the complex were investigated. 展开更多

The title complex crystallizes in the triclinic system, space group P1 with a = 4.7013(9), b = 5.6822(11), c = 17.758(4) ?, α = 87.39(3), β = 85.39(3), γ = 85.76(3)o, V = 471.18(17) ?3, Z = 1, Mr = 481.26, Dc = 1.696 g/cm3, μ = 0.770 mm-1, F(000) = 247, R = 0.0385 and wR = 0.1015. The Mn(II) atom assumes a distorted octahedral geometry, involving four carboxyl oxygen atoms from different m-CPOAH– ligands and two coordinated water molecules. The Mn(II) atoms are linked by the m-CPOAH– ligand to form a one-dimensional chain structure along the a axis. The shortest Mn…Mn separation within the polymer is 7.401(4) ?. A three- dimensional supramolecular network is constructed by O–H…O hydrogen bonding interactions. 展开更多
