One Zn(II) coordination polymer based on imidazole derivative, namely, [Zn(Hiba)2]n (1) (H2iba = 4-(1-H-imidazol-2-yl) benzoic acid) has been synthesized under hydrothermal condition and been characterized by elemental analysis, IR spectroscopy, and single X-ray diffractions. Polymer 1 features 2D (4, 4) layers, which contain single left-handed and right-handed 1D chain. The partially deprotonated Hiba ligands further interlink these 1D chains to form an overall 2D framework. The title polymer exhibited exceptional high thermal stability. The enhanced luminescence of the title polymer is attributed to the coordination of the d10 metal ion to amino-acidlike ligand, followed by formation of ligand to metal charge transfer.
