A new binuclear complex [Sm(p-MOBA)₃bipy]₂ · 2C₂H₅OH (p-MOBA = p-methoxybenzoate, bipy = 2,2′-bipyridine) has been prepared via dissolution reaction in an ethanol/water mixed solution and characterized by elemental analysis, IR, UV, XRD and molar conductance, respectively. Its single crystal was characterized by X-ray single crystal diffraction. The crystal belongs to triclinic system, space group P [graphic removed] . The crystallographic data are: a = 10.970(3) Å, b = 11.507(4) Å, c = 13.931(4) Å, α = 84.449(4)°, β = 76.403(4)°, γ = 87.284(4)°, Z = 1, D r = 1.574 Mg/m³, FW = 1612.02, F(000) = 814, R ₁ = 0.0275, wR ₂ = 0.0646. Two Sm³⁺ ions are linked by four carboxylic groups with bidentate bridging and tridentate chelating-bridging coordination modes. Each center Sm³⁺ is nine coordinated with a distorted tri-capped triangular prism geometry.
