Synthesis, Characterization and Molecular Structure of Iron(III) Complex with Tridentate Diazene Ligand Having O,N,S Donor Set: Coexistence of Octahedral and Tetrahedral Iron(III) Sites in the Asymmetric Unit

Abstract: The reaction of 2-hydroxy-1-(2′-methylthiophenylazo)naphthalene (HL) with iron(II) chloride results in the formation of a hitherto unknown complex, [Fe(L)2][FeCl4] (1). The azo-thioether ligand binds iron(III) center throug

Palladium(II) complexes of terdentate azo ligands with an O,N,S donor set: Synthesis, spectroscopic characterization, X-ray structure and TD-DFT calculations

The reaction of 2-hydroxy-1-(2′-alkylthiophenylazo)naphthalenes (HL1-HL5) and 1-hydroxy-2-(2′-alkylthiophenylazo) naphthalenes (HL6-HL10) with sodium tetrachloropalladate in ethanol medium at room temperature leads to the formation of a new series of complexes of the type [Pd(L)Cl]. All the palladium compounds have been isolated in their pure form and characterized by spectral and elemental analysis data. The crystal structures of [PdL3Cl] (3) and [PdL6Cl] (6) have been determined by single crystal X-ray diffraction as representative cases. The crystal structures show that both complexes have distorted square-planar structures in which he palladium(II) centers are bonded to O1 of the naphtholato function, N2 of the diazene group and S1 at the 2′ position of the phenyl fragment. Therefore, the ligands bind palladium(II) in a tridentate monoanionic [O, N, S] fashion, which give rise to five- and six-membered chelate rings in each case. The fourth coordination site is occupied by a chloride ion. These complexes show intense absorption bands in the visible and UV region. The nature of the electronic transitions has been examined using (TD-DFT) formalism.

Binding of Bi- and Tri-valent Nickel by Azophenolates incorporating Thioether/Ether Donor Sites

Nickel(II) complexes of tri-and hexa-dentate ligands in which the donors are azo nitrogen, phenolic oxygen and thioether sulfur or ether oxygen have been isolated.Structure determination of three complexes has established the presence of distorted octahedral NiN2O2X2 (X = S or O) co-ordination spheres.In dichloromethane solution the nickel(III)-nickel(II) couple is electrochemically observable for the thioether complexes with E1/2 in the range 0.65-0.85 V vs. saturated calomel electrode.The blue-violet nickel(III) species can be quantitatively electrogenerated in solution.Upon freezing (77 K) axial EPR spectra (g ca.2.18, g ca.2.06) compatible with the uncommon hole configuration (d(x2-y2))1 are observed.The ether complexesare more difficult to oxidise and the nickel(III) species are not tractable.This is consistent with the higher strength of nickel-thioether compared to -ether binding.
