A new compound, {[Sm₂L₃(H₂O)₄]·(4,4'-bpy)·3H₂O}_n (1, H₂L=5-(3-pyridyl methoxy) isophthalic acid, 4,4'-bpy=4,4'-dipyridyl), has been hydrothermally synthesized and characterized by single-crystal X-ray diffraction. It crystallizes in triclinic, space group P1 with a=11.266(2), b=15.530(3), c=16.711(3) Å, α=112.803(3), β=90.526(1), γ=94.006(3)°, V=2686.6(9) Å³, Z=2, D_c=1.727 g/cm³, μ=2.251 mm^-1, F(000)=1392, S=0.999, the final R=0.0296 and wR=0.1058. In the title compound, two crystallographically independent Sm³⁺ cations are bridged by the carboxyl group of L^2- ligands to form two different {Sm₂} binuclear subunits which are further connected by two distinct L^2- ligands to shape a 1D chain, and such 1D chains are linked up to generate a 2D coordination polymer by another crystallographically unique L^2- ligand. The thermogravimetric analysis and luminescent property of the title compound were also investigated.
