A copper(II) complex with a thioether and ether containing azophenol ligand: Synthesis, spectra, X-ray structure and DFT computations
摘要:
A new ONSO donor azophenol ligand (HL) having thioether-S and ether-O atoms has been synthesized and characterized by various spectroscopic techniques. The hydrazoketo and azoenol equilibrium of the ligand has been studied by a theoretical study. The copper(II) complex, having the formula [Cu(L)(H2O)](ClO4), has been synthesized and structurally characterized by a single crystal X-ray study. The electronic structures of HL and the Cu(II) complex have been interpreted by OFT studies. The electronic spectra of the compounds have been interpreted by TDDFT calculations.
