Synthesis, Structure, and Properties of 4-Methyl-N-[2-(Pentafluorophenyliminomethyl)Phenyl]Methyl-Benzenesulfamide and the Copper(II) Complex Based on It

A new azomethine compound 4-methyl-N-[2-pentafluorophenyliminomethyl)phenyl]methylbenzenesulfamide and a Cu(II) complex based on it are obtained and characterized by 1 H NMR, IR spectroscopy and the elemental analysis. Crystal structures of azomethine and its complex are analyzed by single crystal X-ray diffraction (XRD). From the single crystal XRD data it is found that the Cu(II) complex crystallizes in the triclinic space group . The unit cell contains two crystallographically independent mononuclear molecules with similar geometries. In the complex, copper ions have a distorted tetrahedral environment of four nitrogen atoms, which is formed by two bidentate coordinated azomethine ligands. From magnetic measurements it is found that the Cu(II) complex is paramagnetic.
