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... 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. 展开更多

A new Pb(Ⅱ) coordination polymer [Pb(L1)(L2)]·1.25H2O has been synthesized with 2-(4-fluorophenyl)-1H-imidazo[4,5-f][1,10]phenanthroline (L1) and sebacic acid (H2L2) under hydrothermal conditions. Crystallographic data: triclinic, space group Pī with a=8.4890(17), b=12.471(3), c=14.604(3), α=67.04(3), β=74.08(3), γ=85.80(3)°, V=1368.0(5)3 , Z=1, C58H59F2N8O10.5Pb2 , Mr=1488.51, Dc=1.807g/cm3 , F(000)=729, μ(MoKa)=6.221mm-1 , R=0.0283 and wR=0.0564. The L2 dianions bridge neighboring Pb(Ⅱ) atoms to form a two-dimensional layer structure. The π-π interactions between the L1 ligands of neighboring layers led to a three-dimensional supramolecular architecture. The IR and TGA of the complex have been studied in detail. 展开更多
