  Fluorinated phenolates in monomeric and dimeric Co(II) compounds

  摘要：

  Five structures of two monometallic cobalt aryloxide compounds and two bimetallic cobalt-thallium compounds with bridging fluorinated aryloxide ligands (OC6F5 = OArF, OC6H3(CF3)(2) = OAr') are presented with magnetic susceptibility and spectroscopic characterization data. The monometallic compounds, [Co(OArF)(2)(DME)](2), 1, and [Co(OAr')(2)(DME)(2), 2, are prepared by metathesis reactions between two equivalents of TlOAr and one of CoI2. The heterobimetallic compounds [Tl2CO(OArF)(4)]center dot 2 toluene, 3a, and [TI2Co(OAr')(4)](2)center dot 2 toluene, 4, were prepared with a 4:1 ratio of the thallium aryloxide to CoI2. An unsolvated form of [Tl2Co(OArF)(4)], 3b, was also structurally characterized. Magnetic susceptibility studies revealed that 3b is a simple, isolated high-spin Co-II with Curie-Weiss behavior. Dimeric compounds 1 and 2 are also high-spin Coll but exhibit antiferromagnetic coupling, via superexchange through two mu(2)-OArF ligands, as supported by DFT calculations. Compound 4 exhibits ferromagnetic behavior which is ascribed to the presence of mu(3)-OAr ligands, instead of mu(2)-OAr groups. (C) 2012 Elsevier Ltd. All rights reserved.
