  Azonaphtholate ligands for the nickel(III) cation: design, synthesis and electrochemical properties

  摘要：

  Nickel(II) complexes of tridentate meridionally spanning azonaphtholate ligands. 1-(2-pyridylazo)-2-naphthol (HL(1)) and 1-(2-methylsulfanylphenylazo)-2-naphthol (HL(2)), have been synthesised. The paramagnetic nickel(ll) centres are six-co-ordinated, including the donor atoms of the pendant arms. In dichloromethane solution the nickel(III)-nickel(II) redox couple was observed by cyclic voltammetry for both the complexes [NiL(2)(1)] and [NiL(2)(2)], E(1/2) being +0.93 and +0.65 V respectively versus saturated calomel electrode. Constant-potential electrolysis generated the nickel(III) complexes in solution. In frozen (77 K) dichloromethane solution the nickel(III) complexes display axial EPR spectra (g(parallel to) approximate to 2.20, g(perpendicular to) approximate to 2.07) indicating an axial compression and (d(x2-y2))(1) ground state. The results demonstrate the significant role of the chelating nature of the ligands and thioether co-ordination in stabi[ising the trivalent nickel centre.
