| Abstract | New tetradentate ligands with N 2 OS coordination spheres were prepared and the corresponding nickel(II) complexes were synthesized and characterized by analytical, spectroscopic and electrochemical methods. The structure of nickel [emthyl2- N -[2-(3′-methyoxy-2′-phenolate)methylidynenitrilo]ethyl]aminato(-1)-1-cyclopentenedithiocarboxylate] has been determined by X-ray crystallography. This complex crystallizes in the orthorhombic space group P 2 1 2 1 2 with a =11.417 (3), b =13.883 (4), c =12.769 (3), Z =4 and R 1 =0.0539 for 4641 reflections with I >2 σ ( I ). The UV-Vis and 1 H NMR spectroscopic results indicate that the complexes have a square-planar structure in the solid state and in solution. Electrochemical and EPR data show that the complexes are reduced to the correspondent nickel(I) complexes, but that the ligands are non-innocent in the electrochemical oxidation of the complexes. |
