Synthesis and reactivity of haloacetato derivatives of iron(II) including the crystal and the molecular structure of [[Fe[(C[F.sub.3]COOH).sub.2][([mu]-C[F.sub.3]COO).sub.2]].sub.n]

The syntheses and reactivity of haloacetates of iron(II) are presented. The isolated compounds are formed due to C-X activation (X = Cl, Br) and haloacetato decomposition, which occurs with concomitant oxidation at the metal centers.
