A Novel Supramolecular Complex Based on Zaltoprofen Ligand: Synthesis, Crystal Structure, and Properties

Abstract

A novel metal-organic supramolecular complex [Zn₂ (Zaltoprofen)₂(phen)₂] (where Zaltoprofen = 5-(1-carboxyethyl)-2-(phenylthio)phenylacetic acid, phen = 1,10-phenanthroline) has been synthesized under hydrothermal condition and characterized by single crystal X-ray diffraction, elemental analysis, spectral method (IR), powder X-ray diffraction (XRD), electronic Spectra (UV-vis), and fluorescent properties. The compound crystallizes in the monoclinic P2(1)/c space group. [Zn₂(Zaltoprofen)₂(phen)₂] features 0-D structural, the π–π stacking interactions and C‒H···O hydrogen-bonds play a vital role in determining the crystal packing and construction of the extended 3-D supramolecular network.
