The structural and electrochemical consequences of hydrogenating copper N2S2 Schiff base macrocycles
摘要:
A series of cis and trans tetradentate copper macrocyclic complexes, of ring size 14-16, that employ amine and thioether donor groups are reported. Apart from 5,6,15,16-bisbenzo-8,13-diaza-1,4-dithiacyclohexadecane copper(I) (cis-[Cu(H4NbuSen)](+)) all of the complexes are obtained in the copper(II) form. Crystallographic analysis shows that the copper(II) complexes all adopt a distorted planar geometry around the copper. In contrast, cis-[Cu(H4NbuSen)](+) is found to adopt a distorted tetrahedral geometry. The complexes were subjected to electrochemical analysis in water and acetonitrile. The effect of the solvent, positions of the donor atoms (cis/trans) on E-1/2 is discussed as is the comparison of the electrochemical behaviour of these complexes with their parent Schiff base macrocycles.
