Thermodynamic stability of Ni(II) and Cu(II) chelates with biladiene-a,c in DMF

Thermodynamic stability of Ni(II) and Cu(II) chelates with biladiene-a,c in DMF The equilibria of the reactions of complex formation between alkyl-substituted biladiene-a,c and Ni(II) and Cu(II) acetates in DMF were studied by the electronic spectroscopy. Porphyrin-like complexes (1:1) were shown to form in the systems under study. Concentration constants of complex formation were calculated and extrapolated to infinite dilution in order to obtain standard thermodynamic quantities. The role of the nature of a metal cation on thermodynamic parameters of complex formation processes was discussed. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Russian Journal of Coordination Chemistry Springer Journals

Abstract

The equilibria of the reactions of complex formation between alkyl-substituted biladiene-a,c and Ni(II) and Cu(II) acetates in DMF were studied by the electronic spectroscopy. Porphyrin-like complexes (1:1) were shown to form in the systems under study. Concentration constants of complex formation were calculated and extrapolated to infinite dilution in order to obtain standard thermodynamic quantities. The role of the nature of a metal cation on thermodynamic parameters of complex formation processes was discussed.
