abstract

  • Two new iron-oxo clusters, viz. di-mu-trifluoroacetato-mu-oxo-bis[(2,2'-bipyridine-kappa(2)N,N')(trifluoroacetato-kappaO)iron(III)], [Fe(2)O(CF(3)CO(2))(4)(C(10)H(8)N(2))(2)], and bis(2,2'-bipyridine)di-mu(3)-oxo-hexa-mu-trifluoroacetato-bis(trifluoroacetato)tetrairon(III) trifluoroacetic acid solvate, [Fe(4)O(2)(CF(3)CO(2))(8)(C(10)H(8)N(2))(2)].CF(3)CO(2)H, contain dinuclear and tetranuclear Fe(III) cores, respectively. The Fe(III) atoms are in distorted octahedral environments in both compounds and are linked by oxide and trifluoroacetate ions. The trifluoroacetate ions are either bridging (bidentate) or coordinated to the Fe(III) atoms via one O atom only. The fluorinated peripheries enhance the solubility of these compounds. Formal charges for all the Fe centers were assigned by summing valences of the chemical bonds to the Fe(III) atom.
