摘要
A trinuclear Fe(III) complex [Fe-3(OAc)(3)L-3] (1), a tetranuclear Mn(III) complex [Mn4Cl4L4] (2) and a tetranuclear Ni(II) complex [Ni-4(MeOH)(4)L-4] (3) have been synthesized from the reaction of simple metal salts with ligands derived from salicylidene-2ethanolamine (H2L). Structural characterization of the three complexes reveals distinctly different topologies, despite the similar coordination modes of the ligand L2-. Preliminary magnetochemical studies have been performed and reveal spin ground states of S = 1/2,8 and 4 for complexes 1, 2 and 3, respectively. (C) 2002 Elsevier Science B.V. All rights reserved.
