Compound 1 exhibits one-dimensional chain structures which are further stacked by π-π interactions to give a supramolecular layer. Finally, the N-H...O hydrogen bonds between the nitrogen atom of L and carboxylate oxygen atom stabilize the structure of 1. 相似文献

A new one-dimensional coordination polymer, [Pb(phen)(ANS)2]n (ANS = 2-ami- nonaphthalene-1-sulfonate, phen = 1,10-phenanthroline), has been prepared by hydrothermal synthesis and structurally characterized by elemental analysis, IR and single-crystal X-ray diffrac- tion. The results determined by XRD reveal that the complex crystallizes in monoclinic, space group P21/c with a = 16.8374(14), b = 16.9825(14), c = 9.9392 (8) , β = 95.9830(10)o, V = 2826.5(4) 3, Mr = 831.86, Dc = 1.955 g/cm3, μ(MoKα) = 6.173 mm-1, F(000) = 1624, Z = 4, the final R = 0.0272 and wR = 0.0694 for 4305 observed reflections (I > 2σ(I)). In the complex, the adjacent lead(II) ions are bridged through the oxygen atoms of sulfonate groups in a syn-syn conformation, yielding an infinite zigzag chain. And the intermolecular N–H···O hydrogen bonds link the chains into two-dimensional layered networks, which are further assembled into a separate two-layer-film-like packing structure. 相似文献

The title coordination polymer, [Pb(L)(1,4-ndc)] 1 (L = 2-(4-fluorophenyl)-1Himidazo[4,5f1,10]phenanthroline, 1,4-ndc = naphthalene-1,4-dicarboxylic acid), has been obtained by using hydrothermal synthesis and characterized by elemental analysis, IR and singlecrystal X-ray diffraction. It crystallizes in monoclinic, space group P21/c with a = 10.1043(11), b = 14.3162(15), c = 17.6061(18), β = 95.3990(10)°, V = 2535.5(5)3, Z = 4, C31H17FN4O4Pb, Mr = 735.68, Dc = 1.927 g/cm3, F(000) = 1416, μ(MoKa) = 6.709 mm-1, R = 0.0201 and wR = 0.0489. The 1,4-ndc dianions link neighboring Pb(II) atoms in a bis-chelating mode, yielding a one-dimensional chain structure along the c axis. The C–H···π interactions between the carbon atom of L ligand and the benzene ring of 1,4-ndc lead the one-dimensional chains to form a two-dimensional supramolecular layer. The π-π interactions between L ligand and 1,4-ndc ligand make the two-dimensional layers generate a three-dimensional supramolecular architecture. Additionally, the N–H···O hydrogen bonds further stabilize the structure of 1. 相似文献

A one-dimensional chain coordination polymer [Cu(phen)(2,4,6-TMBA)2(H2O)]n has been synthesized by reacting 2,4,6-trimethyl-benzoic acid, 1,10-phenanthroline and Cu(Ⅱ) perchlorate and its structure was characterized. Crystal data for this complex: tetragonal, space group I41, a = 2.0293(3), b = 2.0293(3), c = 1.3758(2) nm, α =β= γ = 90°, V= 5.6657(13) nm3, Dc= 1.379 g/cm3, Z = 8, μ(MoKa) = 0.815 mm-1, Mr = 588.14, F(000) = 2456, S = 1.047, R = 0.0459 and wR = 0.1053. The crystal structure shows that two neighboring Cu(Ⅱ) ions are linked together by one bridging-chelating 2,4,6-trimethyl-benzoic group, forming a one-dimensional chain structure. Each Cu(Ⅱ) ion is coordinated with two nitrogen atoms from one 1,10-phenanthroline molecule, three oxygen atoms from three 2,4,6-trimethyl-benzoic acid molecules and one oxygen atom from one water molecule, giving a six-coordinate distorted octahedral coordination geometry. The cyclic voltammetry behavior of the complex was also investigated. 相似文献

The crystal structure shows that two neighboring manganese(Ⅱ) ions are linked together by one 4,4′-bipy molecule, and the whole complex molecule forms a one-dimensional chain structure. Each manganese(Ⅱ) ion is coordinated with two oxygen atoms of two a-naphthaleneacetic acid molecules, two nitrogen atoms of two 4,4′-bipy molecules and two oxygen atoms from two water molecules, giving a distorted octahedral coordination geometry.

1 INTRODUCTION Polymeric manganese complexes with fascinating topological chemistry have received considerable interest[1, 2]. The complexation of phen with man- ganese ion gives rise to a wide variety of coordi- nation complexes; however, (phen)Mn coordina- tion polymers are rare since the chelation of phen results in 1 to 3 5-membered chelating rings, ob- structing the way towards the coordination poly- mer. Similar situation has also been observed for 2,2?-bipyridine (bpy) which has si… 相似文献

1 INTRODUCTION The investigation of coordination polymers has rapidly been expanded in last decade owing to their potential applications such as catalysis, molecular absorption, non-linear and magnetic materials. Among the varieties of such coordination polymers, the po- lymers of cadmium with dicarboxylates having fas- cinating structural topologies and good photolumi- nescence constitute a new family. Many reports are concerned about cadmium dicarboxylate polymers with 1D helix structu… 相似文献

A new cobalt( Ⅱ ) complex [Co(μ-phth)(imi)2]n (phth = o-phthalato, imi = imidazole)has been synthesized by the reaction of CoCl2 with disodium o-phthalate and imidazole. The crystal structure of the compound has been determined by single-crystal X-ray diffraction. The crystal is of monoclinic system, space group Pn with a = 8.405(1), b = 9.995(1), c = 9.996(2) (A),β= 104.479(2),V= 813.0(2) (A)3, Dc= 1.467 g/cm3, C14H12N4O4Co, Mr= 359.21, F(000) = 366,μ = 1.079 mm-1, Z = 2, R = 0.0483 and wR = 0.1209 for 1583 observed reflections (Ⅰ> 2σ(Ⅰ)). In the title complex, the Co(Ⅱ) ions are bridged by o-phthalate ligands in a bidentate mode, producing a zigzag infinite chain structure. Each four-coordinated cobalt( Ⅱ ) center was coordinated by two oxygen atoms and two nitrogen atoms to give a distorted tetrahedral geometry. The chains are linked by hydrogen bonds between oxygen atoms belonging to carboxylate groups and hydrogen atoms of imidazole molecules, forming an unusual two-dimensional coordination polymer. 相似文献

It crystallizes in triclinic, space group P1 with a = 9.153(5), b = 10.338(5), c = 13.074(5), α = 80.956(5), β = 89.725(5), γ = 80.534(5)°, V = 1204.8(10)3 , Z = 1, C54H44F2N8O9Pb2 , Mr = 1401.35, Dc = 1.931 g/cm3 , F(000) = 678, μ(MoKa) = 7.055 mm-1 , R = 0.0277 and wR = 0.0559. Each cis-1,4-chdc anion coordinates with two Pb(Ⅱ) atoms in a bis-chelating coordination mode. In this way, cis-1,4-chdc anions bridged the neighboring Pb(Ⅱ) atoms to generate a 1D chain structure. The L ligands from neighboring chains are paired through the strong π-π interactions to generate a fascinating 2D supramolecular layer. 相似文献
