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 s...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).展开更多
