N,N'-BIS(1-FERROCENYL-1-OXO-3-METHYL)PROPENYLETHYLENEDIAMINE AND ITS METAL-COMPLEXES

A new Schiff base ligand, N,N'-bis(1-ferrocenyl-1-oxo-3-methyl)propenylethylenediamine (H(2)L) and its copper(II), zinc(II), cobalt(II), nickel(II), cadmium(II) and manganese(II) complexes have been prepared, and the structure of the copper complex has been determined by single crystal X-ray techniques and refined to R=0.041 for 7403 independent reflections. The copper atom is situated in a distorted planar environment. The dihedral angle between planes of two chelating rings which do not contain the metal is 33.5 degrees. Two substituted Cp rings are conjugated with two chelating 'acacim' rings. The iron-centroid forms an angle of 179.4 degrees. The Cp rings are twisted from the eclipsed conformation.
