| Abstract: | The zinc(II) coordination polymer Zn2(L)2(bix)2 · 2H2O ( 1 ) H2L = 4,4′‐methylenebis(oxy)dibenzoic acid, bix = 1,4‐bis(imidazole‐1‐yl‐methylene)‐benzene] was synthesized by hydrothermal reaction. The title compound was characterized by single‐crystal X‐ray diffraction analysis, IR spectroscopy, and elemental analysis. The crystal structure determination reveals that compound 1 displays a twofold interpenetrated 3D framework, in which the Zn atoms are connected by the H2L ligands into interesting right and left‐handed helical chains. Topological analysis reveals that the title compound displays a (3,4)‐connected (63) (65 · 8) topology. The solid‐state luminescent spectra was studied. Furthermore, the dispersed solution of compound 1 in DMF exhibits strong fluorescent emission, which could be quenched by trace amount of nitrobenzene. |
