The structure of hexakis--acetato-1:24O:O'; 2:34O:O'; 1:34O:O'-triaqua-1O,2O, 3O-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.
