| Abstract: | The polynuclear complexation of divalent 3d transition metal cations with N,N,N',N'-tetrakis(2-pyridylmethyl)-1,2-ethanediamine (tpen) in aqueous solution was investigated. It was found that copper(II) forms a dinuclear complex with tpen in an aqueous solution containing chloride. The composition of the complex was determined as Cu(2)Cl(2)(tpen)(2+). Furthermore, the stability constant of the complex was determined and its structure was postulated to be (mu-Cl)(2). |
