Zinc Complex with Tridentate ONO Schiff Base Ligand: The Characterization and Nanostructure Thereof

A new Zn(II) coordination complex based on the tridentate ONO Schiff base 2-(((2-methoxyphenyl)imino)methyl)phenolate ligand was synthesized and characterized structurally by using FT-IR, H-1 NMR, C-13{H-1}NMR, UV-Vis and photoluminescence spectroscopies, elemental analysis and single crystal X-ray crystallography (CIF file CCDC no. 2027332). The molecular structure as well as its supramolecular features was studied using structural, Hirshfeld surface analyses as well as computational studies. The supramolecular arrangement of this coordination complex is directed by a series of hydrogen bonding interactions, including O-H center dot center dot center dot O, C-H center dot center dot center dot Br and C-H center dot center dot center dot pi. The C-H center dot center dot center dot pi energies in this compound calculated to be in the range of 5.79-7.99 angstrom. The compound is also successfully synthesized in three different concentrations by ultrasonic irradiation. The product was characterized by different techniques and the morphology was analyzed using field-emission scanning electron microscopy. The comparison between samples synthesized using ultrasonic irradiation demonstrated that lower concentrations of initial reagents decreased plate size and increased the homogenization of particle size distribution.
