Triethyl­ammonium hexa-μ(2)-acetato-κ(12) O:O′-diacetato-κ(2) O-aqua-μ(3)-oxido-triferrate(III) toluene monosolvate

The title compound, (C(6)H(16)N)[Fe(3)(CH(3)CO(2))(8)O(H(2)O)]·C(7)H(8), was serendipitously crystallized from a reaction of disilanol with iron(II) acetate. The trinuclear acetatoferrate(III) anion has a triethyl­ammonium cation as the counterion. The three Fe atoms lie on the vertices of a regular...

Sumario:The title compound, (C(6)H(16)N)[Fe(3)(CH(3)CO(2))(8)O(H(2)O)]·C(7)H(8), was serendipitously crystallized from a reaction of disilanol with iron(II) acetate. The trinuclear acetatoferrate(III) anion has a triethyl­ammonium cation as the counterion. The three Fe atoms lie on the vertices of a regular triangle and are octa­hedrally coordinated. The complete coordination of the anion includes shared ligands among the three metal ions: a central tribridging O atom and six bidentate bridging acetyl groups. The six-coordinations of two of the metal ions are completed by a monodentate acetate ligand, whereas that of the third metal ion is completed by a water mol­ecule. The uncoordinated triethyl­ammonium cation is involved in N—H⋯O hydrogen bonding to a singly coordinated acetyl group. The coordinated aqua mol­ecule is involved in bifurcated O—H⋯O hydrogen bonding. C—H⋯O inter­actions are also observed. The toluene solvent molecule is disordered over two sets of sites in a 0.609 (11):0.391 (11) ratio.
