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

Abstract

A new zinc(ιι) coordination polymer with 2,5-thiophene dicarboxylic acid (H2tda) 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 [Zn2(tda)2(bmib)]n (1), is monoclinic, space group C2/c with a = 14.215 (2), b = 16.579(3), c = 14.711(3) Å, β = 90.823(6)°, V = 3467(2) Å3, Z = 8, Mr = 737.36, Dc = 1.413 g/cm3, F(000) = 1496and μ = 1.553 cm−1. The final refinement gave R = 0.0535 and wR = 0.0682 for 3104 reflections with I > 2σ(I). X-ray diffraction analysis reveals that the title compound [Zn2(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 [Zn2(tda)2(bmib)]n(1) may be a good candidate as a photoactive material.
