Untersuchungen an Metallchelaten mit Liganden des Cuproin- und Ferrointyps. XVII1. Struktur und Bindung von Perchlorato-bis(cuproin)- und Perchlorato-bis(ferroin)-kupfer(II)-Perchloraten

Structure and Bonding of Perchlorato-bis(cuproine)- and Perchlorato-bis(ferroine)-copper(II) Perchlorates The results of ESR, IR, and visible spectra of copper(II) chelates of the type CuL₂ClO₄]ClO₄ (L = bipy, phen, dmp, dmch, and bich) are reported. In all cases evidences for coordinated perchlorate ions were found. On the basis of the ESR and visible spectra the bonding properties of the chelates are discussed.
