Abstract: A one-dimensional complex, [Gd2(PDC)3(phen)(H2O)·H2O]n (H2PDC=pyridine-3,4-dicarboxylic acid, phen =1,10-phenanthroline), has been synthesized under hydrothermal conditions and characterized by elemental analysis, IR, TG analysis, and X-ray single-crystal structure analysis. Crystallographic data for the title complex: C33H21Gd2N5O14, Mr=1 026.05, Triclinic, space group P1, a=0.751 07(15) nm, b=1.256 5(3) nm, c=1.825 7(4) nm, α=70.80(3)°, β=79.00(3)°, γ=76.05(3)°, V=1.567 4(5) nm3, the final refinement gave R=0.022 4 and wR=0.047 5 for 4 913 observed reflections with I>2σ(I). The coordination polymer displays a 1D belt-like chain. The 1D chain connected with adjacent chains through π-π stacking interaction of phen groups to form 2D layers, which are further extended to a 3D supramolecular network through H-bonds interaction.
