Synthesis, characterization and spectral investigation of salen-type cobalt(iii) schiff base complexes. x-ray crystal structure of trans-[Co(Me-Salen)(3-Acetylpyridine)2]ClO4

Article

Abstract

Two new cobalt(III) complexes of the Schiff base N,N′-bis(methylsalicylidene)-1,2-ethylenediimine dianion (Me-Salen), trans-[Co(Me-Salen)(L)2]ClO4 (L = 3-acetylpyridine) (I) and (L = 4-acetylpyridine) (II), have been synthesized and characterized by elemental analyses, FT-IR, UV-Vis, and 1H NMR spectroscopy. The X-ray diffraction analysis reveals that I crystallizes in the monoclinic space group P21/c and displays a distorted octahedral coordination geometry about Co with the equatorial plane formed by the N2O2 donors of the tetradentate Schiff base dianion, the two phenolate O atoms and the two imine N atoms of which are each mutually in cis-position. Two 3-acetylpyridine molecules are attached to the metal atom to fill its axial positions.
