A two-dimensional coordination polymer, [Pb(bmzbc)2]n (1) (Hbmzbc = 4-benzimi- dazole-1-yl-benzoic acid), has been synthesized by the solvothermal reaction of Pb(NO3)2 with Hbmzbc at 120 oC in ethanol solvent. Compound 1 has been characterized by single-crystal X-ray diffraction, powder X-ray diffraction, thermogravimetry analysis, and IR spectrum. Compound 1 crystallizes in the orthorhombic system, space group Pccn, with a = 12.5801(7), b = 20.0795(11), c = 9.1830(6) Å, V = 2319.6(2) Å3, Z = 4, C28H18N4O4Pb, Mr = 681.65, Dc = 1.952 g/cm3, μ = 7.319 mm-1, F(000) = 1312, the final R = 0.0336 and wR = 0.0965 for 1699 observed reflection with I > 2σ(I). In 1, the bmzbc– ligands bridge the Pb(II) ions to generate a 2-D sheet with (4, 4) topology. The complex exhibits turquoise photoluminescent emission with a maximum at 480 nm upon excitation at 300 nm.
