Abstract
The electrochemical synthesis and physico-chemical properties of neutral copper(II) complexes of Schiff bases derived from 2-(2-aminoethyl)pyridine and substituted salicylaldehydes are presented together with the X-ray structure of bis{N-[2′-(2″-pyridyl)ethyl]-4,6-dimethoxysalicylideneiminato}-copper(II). The crystals are monoclinic, with a= 9.871(3), b= 8.208(8), c= 18.230(4)Å, β= 93.85(2)°, space group P21/c, 1 577 reflections with |I∘| > 3σ|I∘|, R= 0.039. The copper atom has a square-planar geometry and the pyridyl nitrogen atoms are not co-ordinated. An extension of the electrochemical synthesis to metal complexes of Schiff bases derived from 4(5)-[(2-aminoethyl)thiomethyl]imidazole and o-hydroxyacetophenones is also reported.Keywords
