A Zinc Coordination Polymer Assembled from bis(4-(1H-Imidazol-1-yl)Phenyl)Methanone and Phthalic Acid: Synthesis, Structural Characterization, and Fluorescent Properties

Abstract

A zinc coordination polymer with the formula [Zn(pa)(L¹)(H₂O)₂]_n (I) (L¹ = bis(4-(1H-imidazol-1-yl) phenyl)methanone, H₂pa = phthalic acid) is synthesized and structurally characterized. The single crystal X-ray diffraction analysis shows that Zn1 has a distorted octahedral geometry with two O atoms from two pa²⁻ ligands and two N atoms from two L¹ ligands. Each L¹ acts as a bridging ligand to link the neighboring zinc ions to form a looped chain. The thermal stability and fluorescent properties of the complex are investigated.
