Synthesis and characterisation of copper complexes with N-ferrocenoyl-N′-aryl(alkyl)thioureas

The treatment of CuCl2·2H2O with ferrocenoyl-substituted thioureas of the type FcC(O)NHC(S)N′HR (Fc=ferrocenyl; R=C6H5; C6H4-p-OMe; C6H4-p-C(O)Me; C6H4-o-Me; C6H4-o-Cl; C6H4-o-NO2; i-Pr) gives the corresponding copper(I) derivatives with the metallic centre in an unusual coordination mode. The complexes were characterised by spectroscopic methods and X-ray diffraction studies. The electrochemical behaviour of these compounds was also investigated.
