The self-assembly of 1,10-phenanthroline（phen） and 1,3-benzenedicarboxylic acid（H2bdc） with Pb（NO3）2 under solvothermal conditions in N,N-dimethylacetamide（DMA） gives rise to a one-dimensional chain coordination polymer, [Pb（phen）（bdc）]（1）, which was characterized by elemental analysis, FT-IR and single-crystal X-ray diffraction. This complex crystallizes in triclinic, space group P1 with a = 7.5595（6）, b = 9.8199（8）, c = 13.1663（11） , α = 69.7590（10）, β = 80.6000（10）, γ = 71.3180（10）o, Z = 2, C20H12N2O4Pb, Mr = 551.51, Dc = 2.112 g/cm3, F（000） = 520 and μ = 9.757 mm-1. The final R = 0.0304 and wR = 0.0763 for 3427 observed reflections with I 〉 2σ（I） and R = 0.0365 and wR = 0.0894 for all data. The structure contains one crystallographic unique Pb（Ⅱ） atom, one phen molecule chelating with a Pb（Ⅱ） atom, and one bdc2- anion, acting as a bidentate bridging ligand linking the Pb（Ⅱ） atoms to form a one-dimensional structure. The two-dimensional layer and three-dimensional stacking structures are formed by C–H···O hydrogen bonding interactions. The thermal stable and fluorescent properties of 1 were investigated. PbO micro-crystal particles are produced by calcination of powder sample of complex 1. The obtained PbO is characterized and observed by XRD and SEM analyses.
The title complex [Sm2（bdc）3（phen）2]n （1, H2bdc = 1,3-benzenedicarboxylic acid, phen = 1,10-phenanthrolin）, a new samarium（III） complex based on ligand H2bdc and 1,10-phen- anthrolin, has been hydrothermally synthesized and characterized by elemental analysis, FT-IR, and single-crystal X-ray diffraction. The crystal structure reveals that the Sm（1） centre adopts an eight-coordinated distorted square anti-prism coordination geometry, while the Sm（2） centre adopts a nine-coordinated distorted monocapped square prism coordination geometry. The ligand bdc2- takes two different connecting modes and links the Sm（llI） centers to give rise to a 2D network structure. Further, 2D layers of 1 are connected together to form a 3D structure through C-H-O hydrogen bonding interactions. The luminescent property and thermal stability of complex 1 are studied. 1 belongs to the triclinic system, space group P1 with a = 10.7367（5）, b = 14.3750（7）, c = 13.7505（3）A, a = 92.8840（10）, β = 104.4010（10）, ）, = 98.1400（10）°, Z= 2, V= 2143.44（18） A3, Mr = 1153.44, Dc = 1.787 g/cm3, F（000） = 1128,μ= 2.784 mm-1, the final R = 0.0279 and wR = 0.0720 for 8226 observed reflections with 1 〉 2σ（I）.
