Abstract

Two new pseudohalide bridged di- and poly-nuclear copper(II) complexes [Cu₂(L)₂(µ_1,1-N₃)₂] (1), [Cu(L)(µ_1,3-NCS)]_n (2), [LH = C₆H₅C(O)NHN{double bond, long}C(CH₃)C₅H₄N] have been synthesised and characterised by elemental analysis, IR and UV-Vis spectral studies. Structures of both the complexes have been established by X-ray crystallography. A tridentate hydrazone ligand (LH) obtained by the condensation of benzhydrazide and 2-acetylpyridine is used for the preparation of complexes 1 and 2. Variable temperature magnetic susceptibility measurement studies indicate there is a weak ferromagnetic interaction between the two copper(II) ions in 1 (J = +0.75 cm^-1), while weak antiferromagnetic interaction is observed with J values -0.23 cm^-1 for 2. © 2007 Elsevier Ltd.
