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

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.     

A Novel 3D Coordination Polymer Based on Bridging Interactions of the Pyridine-2,3-dicarboxylic Acid

A novel three-dimensional (3D) coordination polymer [Cd(pdc)Cl]_n (1) has been synthesized under hydrothermal conditions, containing pyridine-2,3-dicarboxylic acid (H₂pdc) as a bridging ligand. X-ray analysis shows an infinite 3D structure in which the cadmium(II) centers are bridged by multidentate H₂pdc ligand. The novel complex was characterized by IR spectrum, elemental analysis, fluorescent properties, thermogravimetric analysis, single-crystal X-ray diffraction, and powder X-ray diffraction (PXRD).
