Via the solvothermal reactions of Zn(NO3)(2), H(2)tdc and bib, a new Zn(II) coordination polymer, namely [Zn(tdc)(bib) 0.5(H2O)] n (1 H(2)tdc D 2,5-thiophenedicarboxylic acid, bib D 1,4-bis(imidazolyl) butane), was obtained. The crystal crystallizes in orthorhombic Pbcn space group, a = 11.6785(4) angstrom, b = 11.6776(6) angstrom, c = 19.8439(7) angstrom, alpha = b = gamma D 90 degrees, Z = 8. The single X-ray structural analysis reveals that compound 1 features a 8-fold interpenetrated 3D framework with 3-connected ths topology. In addition, the solid state luminescent property of 1 was also investigated at room temperature.
