Issue Date: | 1-Jan-2014 | Journal: | Journal of the Serbian Chemical Society | Abstract: | The diimine-dioxime ligand, 3,3'-(1,4-butanediyl-dinitrilo)bis-2- -pentanone, 2,2'-dioxime (LH2), containing a N4 donor set was prepared by the Schiff base condensation of 2-hydroxyimino-3-pentanone and 1,4-diaminobutane in two ways: in a protic and in an aprotic solvent. A higher yield of the (LH2) imine was obtained when the synthesis was performed using a protic solvent (C2H5OH) instead of aprotic benzene (78 and 30 %, respectively). The Cu(II) metal complex of diimine-dioxime was synthesized in CH3OH from the perchlorate salt of LH2 in a 1:1 mole ratio. The isolated complex was characterized by the elemental analysis, IR spectroscopy and cyclic voltammetry. The structure of [Cu2(LH)2](ClO4)2 was determined by single-crystal X-ray diffraction analysis. Comparison with structurally related diimine-dioxime Cu(II) complexes revealed the influence of a weak Cu...O(perchlorate) interaction on the geometry of the metallocycle. © 2014 SCS.
