Design and Structural Investigation, Hirschfeld Surface Analysis, and Photoluminescent Behavior of a Cd(II) Coordination Polymer With 4‐Acetylphenoxyacetic Acid Ligand

In this study, we successfully designed and synthesized a novel one‐dimensional Cd(II) coordination polymer, [CdL 3 ] n [HL = 4‐acetylphenoxyacetic acid], employing 4‐acetylphenoxyacetic acid as both a chelating and bridging ligand. The structural features of the Cd(II) coordination polymer were analyzed using infrared (IR) spectroscopy, the thermogravimetric and differential thermal analysis, and single‐crystal x‐ray diffraction. The results indicated that the Cd(II) ion adopts a distorted pentagonal pyramidal coordination geometry involving seven oxygen atoms from five different 4‐acetylphenoxyacetate ligands. This configuration forms a one‐dimensional chain structure through the bridging interactions of the oxygen atoms in the ligands. The Hirschfeld surface analysis was implemented to examine intermolecular interactions within the Cd(II) coordination polymer. Furthermore, the photoluminescent properties of the Cd(II) coordination polymer were investigated in ethanol, indicating that the studied material has the potential to exhibit luminescent properties.
