dc.description.abstractWe report the synthesis, characterization, crystal and molecular structure as well as the spectroscopic, electrochemical and magnetic properties of an unexpected trinuclear copper(II) complex (1), made of three Cu(2-TTA)2 units (2-TTA = 2-thenoyltrifluoroacetone) bridged by two 4'-(3-methyl-2-thienyl)-4,2′:6′,4″-terpyridine (4-stpy) ligands. The central Cu(II) atom shows an octahedral geometry, while the lateral metal centers present a slightly distorted square pyramidal coordination sphere. It is suggested that the introduction of the relatively bulky substituent groups (2-thienyl and [sbnd]CF3) in the 2-TTA ligand are responsible of this uncommon coordination mode. The magnetic behavior of 1 is reported in terms of a combination of monomer and dimer units, leading to weak antiferromagnetic interaction (J = −1.93 cm−1). The cyclovoltammogram of 1 exhibits, in the cathodic potential region, three redox events due to Cu2+/Cu+ and Cu+/Cu0 redox couples and to the mono-electronic reduction of the 4-stpy ligand. © 2017 Elsevier B.V.es
