摘要：

A coordination polymer, [Pb-2(L1)(2)(L2)(2)] (1) (H(2)L1=succinic acid and L2=2-(4-fluoropheny1)-1H-imidazo [4,5-f][1,10]phenanthroline), has been hydrothermally synthesized and characterized by elemental analysis, IR spectroscopy, TGA and single-crystal X-ray diffraction. Crystal data: C46H30F2N8O8Pb2, monoclinic, space group P2(1)/c, a=0.795 40(10) nm, b=2.649 0(3) nm, c=1.996 9(2) nm, beta=99.784(2)degrees, V=4.146 3(9) nm(3), Z=4, R=0,038 0, wR=0.0845. In 1, each L1 anion in a bis-chelating mode bridges Pb(II) atoms to afford a one-dimensional (1D) chain structure. Neighboring 1D chains are linked together by pi-pi stackings among L2 ligands to yield a 3D supramolecular architecture. Finally, the N-H center dot center dot center dot O hydrogen-bonding interactions further stabilize the 3D supramolecular structure of 1.
