A new coordination polymer [Ni(3-bpo)(/M-bdc)(C2H5OH)2]n (1, 3-bpo=2,5-bis(3-pyridyl)-1,3,4-oxadiazole, m-H2bdc=1,3-benzenedicarboxylic acid) was solvothermally synthesized and characterized by IR, TGA and single-crystal X-ray diffraction. The title complex crystallizes in the orthorhombic system, space group Pnma with a=7.786(3), b=17.253(6), c=18.478(6) A, V= 2481.9(14) (A)3, Mr=539.18, Dc=1.443 g/cm3, Z= 4, R=0.0353 and wR=0.0589. The m-bdc and 3-bpo bridge two Ni(II) ions through two carboxylate groups and two pyridyl groups forming a ID infinite double-sinusoidal chain along the c axis. The photoluminescence of 1 shows a large red shift compared to that of free ligands in the solid state.
