Abstract

Synthesis and single crystal X-ray diffraction studies of four transition metal complexes [Mn(L1)](ClO4)2 (1), [Cu(L 1)](ClO4)2 (2), [Ni2(L 2)(NCS)6][Ni(L1)] (3) and [Mn(bzpy)(NCS) 2] (4) with neutral ligands [L1 = N-(1-pyridin- 2-yl-phenylidene)-N′-[2-({2-[(1-pyridin-2-yl phenylidene)amino]ethyl} amino)ethyl]ethane-1,2diamine, L2 = N-(1-pyridin-2-yl-phenylidene)- N′-[2-({2-[(1-pyridin-2-ylphenylidene)amino]ethyl}piperazine-1yl)ethyl] amine, bzpy = 2-benzoylpyridine] are reported. The trinuclear nickel(II) complex 3 is made of a dinuclear anion and a mononuclear cation. Variable-temperature magnetic susceptibility and variable-field magnetisation studies performed on 3 suggest weak antiferromagnetic coupling (J = -0.7 cm-1) between the twometals of the dinuclear entity, but no magnetic interaction between the anionic and cationic counterparts. © 2011 Elsevier Ltd.
