, p. 92 - 98 (2015)
Synthesis of thioether containing NSNO donor azo ligand (HL) showing hydrazoketo and azoenol tautomerism has been performed. The hydrazoketo and azoenol equilibrium of HL has been studied. The hydrazoketo form of HL is predominating over azoenol form. In
Cu(II) complexes of a new tetradentate N 2SO donor: Synthesis, structure, electrochemistry, and DFT computation

, p. 4067 - 4079 (2013)
Cu(II) complexes having distorted square pyramidal geometry with N2SO donor azo-thioether ligand, [Cu(L)X] (X = Cl (1) and Br (2)), have been synthesized and characterized. The geometries of the complexes are confirmed by single crystal X-ray analysis. The complexes form supramolecular 1D chains by intermolecular H-bonding and π-π interaction between the pyridines. Spectral and electrochemical properties have been studied. Electronic structure and spectral properties are explained by DFT and TDDFT analysis. 2013

The ruthenium(III) complexes, cis-(Cl,Cl)-[Ru(L)Cl2] (1) and trans-(Cl,Cl)-[Ru(L)Cl2] (2) with NSNO donor azo functionalized ligand (HL) have been synthesized and characterized by several spectroscopic techniques. Geometry of cis-(Cl,Cl)-[Ru(L)Cl2] (1) has been confirmed by single crystal X-ray study. X-ray structure of 1 suggests pseudo octahedral geometry around Ru with cis-(Cl,Cl) arrangement. Reversible Ru(III)/Ru(II) reduction couple along with irreversible Ru(III)/Ru(IV) oxidation has been observed for the complexes. The complexes catalyze the oxidation of alcohols to aldehydes and ketones in presence of NMO as co-oxidant with moderate to high yields. The electronic structure and solution spectra of the complexes have been supported by DFT and TDDFT calculations.
