Magnetic measurements, UV-Vis spectroscopy, and XAS of dinuclear nickel(II) complexes of bistetraazamacrocycles
Résumé
The nickel(II) complexes of N,N′-xylylenebis(tetraazamacrocycles) have been isolated. The description of these dinuclear bismacrocyclic complexes have been carried out by means of magnetic measurements and spectrophotometric experiments (UV-Vis). The metal environment and the ligand shape have been specified by XANES and EXAFS experiments, since attempts to obtain suitable crystals failed. © 2004 Elsevier Ltd. All rights reserved.
