Ligational behaviour of electrochemically synthesized copper(II) complexesof diethyl 2,3-dioxopentanedioate-2-arylhydrazone derivatives

Cu(II) complexes of diethyl 2,3-dioxopentanedioate-2-arylhydrazone derivati ves have been prepared electrochemically. Their ligational behaviour has be en studied using elemental analyses, IR and electronic spectra, magnetic mo ments and thermogravimetric studies. This work revealed that the structure of the synthesized complexes and their spectral behavior depend, to some ex tent, on the type and nature of substituents on each ligand. The arylhydraz ones under investigation act as alpha-arylhydrazone eater as well as beta-k eto eater. Electronic spectra suggest a square-planar structure of the comp lexes.
