A New Zn(II) Coordination Polymer With Two-Fold pcu Topological Net Based on Dicarboxylate and Imidazole-Containing Ligands: Synthesis, Crystal Structure, and Luminescent Property

A new zinc() coordination polymer with 2,5-thiophene dicarboxylic acid (H(2)tda) and 1,4-bis(2-methyl-1H-imidazol-1-ylmethy) benzene(bmib) has been prepared by hydrothermal synthesis and characterized by single-crystal X-ray diffraction, IR, and EA. Complex [Zn-2(tda)(2)(bmib)](n) (1), is monoclinic, space group C2/c with a = 14.215 (2), b = 16.579(3), c = 14.711(3) angstrom, = 90.823(6)degrees, V = 3467(2) angstrom(3), Z = 8, M-r = 737.36, D-c = 1.413g/cm(3), F(000) = 1496and = 1.553cm(-1). The final refinement gave R = 0.0535 and wR = 0.0682 for 3104 reflections with I > 2 sigma(I). X-ray diffraction analysis reveals that the title compound [Zn-2(tda)(2)(bmib)](n) (1) displays a twofold interpenetrating three-dimensional pcu network. Furthermore, the luminescent property of complex 1 is investigated, which demonstrates that [Zn-2(tda)(2)(bmib)](n)(1) may be a good candidate as a photoactive material.
