Two new pseudohalide bridged di- and poly-nuclear copper(II) complexes [Cu2(L)2(μ1,1-N3)2] (1), [Cu(L)(μ1,3-NCS)]n (2), [LH = C6H5C(O)NHNC(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.
