Abstract
The synthesis and structural determination by X-ray crystallography of four amide copper(II) complexes has been performed: [Cu{OC[(CH2)2N(CH2C6H4X)(CH2CH2C5H4N)]NH(CH2)nPh}(solv)][CF3SO3]2(X = H, solv = H2O, n= 2 1 or 1 2; X = OH, solv = H2O, n= 2 3; solv = MeCN, n= 1 4). In all complexes the co-ordination around the copper atom is a more or less distorted square-based pyramid where the three ligands of the square are unchanged: one oxygen atom of the amide group and two nitrogen atoms of the pyridine nucleus and of the tertiary amine. The fourth ligand is a water molecule (1–3) or an acetonitrile solvent molecule (4). The axial ligand is the oxygen atom of the phenolic group in complexes 3 and 4, while in 1 and 2 this site is occupied by an oxygen atom of a triflate counter ion.Keywords
