-FERROCENYL-1-OXO-3-METHYL)PROPENYLETHYLENEDIAMINE AND ITS METAL-COMPLEXES

A new Schiff base ligand, -ferrocenyl-1-oxo-3-methyl)propenylethylened iamine (H(2)L) and its copper(II), zinc(II), cobalt(II), nickel(II), c admium(II) and manganese(II) complexes have been prepared, and the str ucture of the copper complex has been determined by single crystal X-r ay techniques and refined to R=0.041 for 7403 independent reflections. The copper atom is situated in a distorted planar environment. The di hedral angle between planes of two chelating rings which do not contai n the metal is 33.5 degrees. Two substituted Cp rings are conjugated w ith two chelating 'acacim' rings. The iron-centroid forms an angle of 179.4 degrees. The Cp rings are twisted from the eclipsed conformation .
