The title complex Sm2(bdc)3(phen)2n (1, H2bdc = 1,3-benzenedicarboxylic acid, phen = 1,10-phenanthrolin), a new samarium(Ⅲ) complex based on ligand H2 bdc and 1,10-phenanthrolin, 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 bdc 2-takes two different connecting modes and links the Sm(Ⅲ) 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), α = 92.8840(10), β = 104.4010(10), γ = 98.1400(10)o, Z = 2, V = 2143.44(18)3 , 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 Ⅰ > 2σ(Ⅰ).
