Abstract

Two dinuclear copper(II) complexes, [Cu2(L)2(1,1-NCO)2] (1) and [Cu2(L)2(1,3-NCS)2]H2ODMF (2) have been synthesized using a tridentate N2O donor Schiff base ligand (HL) [1((2-(ethylamino)ethylimino)methyl)naphthalen-2-ol] and characterized by elemental analysis, spectral study and X-ray crystallography. Both complexes are centrosymmetric dimers in which square pyramidal copper(II) centres are connected by pseudo-halides; end-on cyanate in 1 and end-to-end (EE) thiocyanate in 2. Variable temperature (2–300 K) magnetic susceptibility measurements indicate the presence of ferromagnetic exchange coupling between copper(II) centres in complex 1 (J = 0.97 cm-1), and antiferromagnetic exchange coupling in 2 (J = - 0.6 cm–1).
