An Oxo-Centered Trinuclear Cobalt(II)-Diiron(III) Acetate-Aqua Complex

The structure of hexakis-[mu]-acetato-1:2[kappa]⁴O:O'; 2:3[kappa]⁴O:O'; 1:3[kappa]⁴O:O'-triaqua-1[kappa]O,2[kappa]O, 3[kappa]O-[mu]₃-oxo-cobalt(II)diiron(III) dihydrate, [CoFe₂O(C₂H₃O₂)₆(H₂O)₃].2H₂O, is reported. The compound is isostructural with the related mixed-valence trinuclear iron(II,III,III) acetate-aqua complex, [Fe₃O(C₂H₃O₂)₆(H₂O)₃].2H₂O. The coordination geometries around the three metal atoms of the cobalt-iron complex are almost identical to those of the trinuclear iron complex, and the Co and Fe atoms cannot be distinguished.
