Abstract
A new dialkoxo-bridged diiron(III) complex, [Fe-2(N-3)(2)(L)(2)](ClO4)(2) ( 1) [HL = bis(benzimidazol-2-ylmethyl)(2-hydroxyethyl)amine], was synthesize d and characterized. According to X-ray crystallographic studies on the sol vated species 1 . 2C(2)H(5)OH, each Fe(III) ion lies in a highly distorted octahedral environment, and two Fe(III) ions are bridged by the ethoxyl oxy gens from two L ligands. Cryomagnetic analyses indicated a moderate antifer romagnetic interaction between the high-spin Fe(III) ions, with J = -21.3 c m(-1). (C) 2001 Elsevier Science B.V. All rights reserved.
