Abstract

Abstract : A new Co(ΙΙ) complex, [Co2 (L)2 ]·CH3 COCH3 based on an asymmetric Salamo-type ligand (H2 L, 5-methoxy-4', 6'-dibromo-2, 2'-[ethylenedioxybis(nitrilomethylidyne)]diphenol) has been synthesized and characterized structurally by elemental analyses, IR, UV-Vis, and fluorescence spectra. The X-ray crystal structure shows the Co(II) ion is pentacoordinated with geometry of a distorted square-pyramidal symmetry. The Co(ΙΙ) complex consists of two Co(ΙΙ) ions, two deprotonated L 2– units, and one noncoordinated acetone molecule. Each Co(ΙΙ) complex molecule links four other molecules into an infinite 2D supramolecular structure. Meanwhile, the Co(II) complex exhibits emission with the maximum emission wavelength λmax = 432 nm when excited at λex = 349 nm.
