AN OXO-CENTERED TRINUCLEAR COBALT(II)-DIIRON(III) ACETATE-AQUA COMPLEX

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