Summary
The synthesis, characterization and voltammetric and magnetic behaviour of a series of dinuclear complexes μ-(2,5-DPP)[M(hfacac)2]2, in which hfacac is hexafluoro-acetylacetonate, 2,5-DPP is 2,5-bis(2-pyridyl)pyrazine and M = copper(II), nickel(II) and cobalt(II), are described. As with the dinuclear complexes derived from 2,3-bis(2-pyridyl)-pyrazine (2,3-DPP) and analogous ligands, magnetic measurements show that these systems are not coupled. On the basis of magnetic data, we propose that, in contrast to related ligands such as 2,2′-bipyridyl, the coordinated 2,5-DPP cannot be planar.
