    A metal-organic coordination polymer {[La(PDC)(N-HPDC)]·H2O}n (1) (H2PDC=pyridine-3A-dicarboxylic acid) has been hydrothermally synthesized and structurally characterized by X-ray diffraction single-crystal structure determination, elemental analyses and IR spectroscopy. The complex crystallizes in the monoclinic system, space group P21/c with a=1.452 8(2) nm, b=0.681 59(11) nm, c=1.464 0(2) nm, β=94.270(2)°, V=1.445 6(4) nm3, Dc=2.243 reflections (I>2σ(I)). There are La-O-C-O-C-La double chains in the complex. The chelating carboxylate O atoms and pyridyl N atoms lead the compound to 2D layers structure, which is extended to 3D supramolecular architecture through intermolecular hydrogen bonds. It is interesting that the polymer containing one-dimensional channels. CCDC: 708868.
