Abstract
dc.description.abstract
The synthesis, magnetic and structural characterization of two tetrameric copper(II) complexes
{N(C4H9)4}-[Cu2(LH)2(l4-Br)Cu2(LH)2](PF6)4 (1) and [Cu2(LH)2(l4-Cl)Cu2(LH)2](Cl)2(PF6) (2) is described.
LH stands for the hemi-deprotonated anion of the tripodal aminophenol ligand N-(2-pyridylmethyl)-
N,N-bis-[20-hydroxy-50-methyl-benzyl]-amine. The complexes are tetrametallic species formed around
the central halide ion which behaves as an anion template for the formation of the tetranuclear species,
by bridging two dimeric phenoxo bridged [Cu2(LH)2]2+ units. The magnetic behaviour is dominated by the
strong antiferromagnetic exchange within the dimeric unit, mediated by the phenoxo bridges:
J = -439(4) cm-1, g = 2.10(2) for (1) and J = -429(2) cm-1, g = 2.090(9) for (2).
