中文摘要	Four new Cu-II complexes of formulae [Cu-3(SE)(2)(H2O)(2)Cl-3]Cl.6H(2)O (1), Cu-3(SE)(2)(N-3)(4)(DMF)(2) (2), Cu(SE)N-3.DMF (3) and Cu(SE)N-3.Cu(SE)N-3 (4) with tridentate Schiff-base ligands SE-, derived from condensation of N,N-dimethylethylenediamine with salicylaldehyde, have been synthesised and characterised by IR spectroscopy, X-ray structural analyses and variable-temperature magnetic susceptibility measurements. Complex 1 has an alternating phenoxy- and chloro-bridged 1D chain structure. Complex 2 possesses trinuclear units in which the Cu-II ions are bridged by single end-on (mu-1,1) azido ligands. Uniformly spaced 1D chains with end-to-end (mu-1,3) azido bridges are found in 3 and 4. As expected, complexes 1 and 2 exhibit antiferromagnetic and ferromagnetic exchange, respectively. Compounds 3 and 4 show unusual ferromagnetic coupling though the 1,3-azido pathways. Theoretical simulations have been carried out in order to evaluate the magnitude of the magnetic exchange and the magneto-structural correlation has been investigated. (C) Wiley-VCH Verlag GmbH & Co.
