Abstract: A trinuclear Fe(III) complex [Fe₃(OAc)₃L₃] (1), a tetranuclear Mn(III) complex [Mn₄Cl₄L₄] (2) and a tetranuclear Ni(II) complex [Ni₄(MeOH)₄L₄] (3) have been synthesized from the reaction of simple metal salts with ligands derived from salicylidene-2-ethanolamine (H₂L). Structural characterization of the three complexes reveals distinctly different topologies, despite the similar coordination modes of the ligand L^2-. 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.
