Synthesis, Crystal Structure and Spectroscopic Studies of 2-{(E)-[2-Hydroxyphenyl)imino]methyl} Phenol Schiff Base Molecule

Abstract

A new Schiff-base complex 2-{(E)-[2-hydroxyphenyl)imino]methyl}phenol has been synthesized and characterized by elemental analyses, UV-VIS and IR spectroscopy and single crystal X-ray determination. The structure comprises two independent and similar molecules. The two independent molecules in the asymmetric unit are hydrogen bonded and have different conformations. In each molecule, C13H11NO2, adopt an E configuration about the azomethine C-N double bond. The complex crystallized in the triclinic space group P-1. Two benzene rings and azomethine group are practically coplanar, as a result of intramolecular hydrogen bonds involving the hydroxy O atom and azomethine N atom. Also hydroxy group of the molecule is the presence intermolecular O-H center dot center dot center dot O hydrogen bonds with the hydroxy group of the other molecule.
