摘要：

Two new pseudohalide-bridged copper(II) complexes [{Cu(PBH)(mu(1,1)-CNO)}(2)] (1) and {Cu(PBH)(mu(1,5)-NCNCN)}(n) (2) (where HPBH = 2-pyridinecarboxaldehyde benzoyl hydrazone) have been synthesised and characterised by elemental analysis, CV, IR and UV-Vis spectral studies. The tridentate hydrazone pro-ligand (HPBH) was obtained by the condensation of benzhydrazide and pyridine-2-carboxaldehyde. Structures of both complexes have been established by X-ray crystallography which shows that 1 is a mu(1,1)-CNO--bridged dimer whereas 2 is a mu(1,5)-dca-bridged (dca = dicyanamide) linear polynuclear structure. Variable temperature magnetic susceptibility studies indicate weak antiferromagnetic interactions with J values -0.50 cm(-1) and -0.10 cm(-1) for 1 and 2, respectively. (C) 2008 Elsevier B.V.
