  摘要：

  A new 2,2'-bipyridine-based phosphadithiamacrocycle: 3,3'-5-phenyl-2,8-dithia-5-phospha[9]-2,2'-bipyridinophane (L) has been synthesized by reacting 6,6'-bis(bromomethyl)-2,2'-bipyridine and dilithium 3-phenyl-3-phosphapenta-1,5-dithiolate. The phosphoryl derivative: 3,3'-5-oxo-5-phenyl-2,8-dithia-5-phospha[9]-2,2'-bipyridinophane (Lox) synthesized by direct oxidation of L at open atmosphere. Both compounds have been isolated as white solids containing different amounts of LiBr.The reaction of acetonitrile solutions of these solids with Fe(II) perchlorate gave the complexes [FeBr(L)](ClO4) center dot 2H(2)O and [FeBr(Lox)](ClO4) center dot 3H(2)O, which were crystallized as [FeBr(L)]Br center dot H2O and [FeBr(Lox)](ClO4) center dot 1 1/6 MeOH salts from nitromethane or methanol, respectively. Both compounds were characterized by X-ray diffraction analysis. In both cases, a distorted octahedral environment is achieved at the Fe(II), with five sites occupied by the macrocycles L and Lox and the sixth by a monodentate bromine ligand. The bond distances found in the complex cation [FeBr(Lox)](+) are compatible with a high-spin configuration. However, the same parameters for [FeBr(L)](+) and their magnetic character are only compatible with a low-spin configuration. (c) 2005 Elsevier Ltd. All rights reserved.
