Magneto-Structural Correlations in μ-Halo Bridged Copper(II) Chains

subject

description

To design synthetic pathways to systems of desired properties is a growing challenge for inorganic chemist. Our current interest in this area is focused on copper(II) chemistry. Besides to advance in the understanding of the factors determining the conformation around copper(II) in the solid state, we intend to gain insight into the chemical and structural effects that govern exchange coupling interactions in condensed species. In this context, we have approached the synthesis and characterization of a wide set of pentacoordinated Cu(LIII)XY complexes (LIII=tridentate ligand, X=coordinating anion, Y=coordinating or non-coordinating anion) showing a great structural diversity (including mono, bi and polynuclear species)1–4. Tridentate rigid “quasi-planar” ligands such as terpy (2,2′:6′,2″-terpyridine), paphy (pyridine-2-aldehyde-2′-pyridylhydrazone) and TPT (2,4,6-tris(2-pyridil) -1,3,5-triazine) favour the stacking of (Cu(LIII)X)+ entities to give dimers or other condensed systems (simple or ladder-like chains) when X is a potentially bridging anion1–3.
