Abstract

Single crystals of a new mixed-valence compound, [Fe7(C 4H9NO2)6Cl 6]·2CH3CN·H2O, were synthesized by solvothermal methods. The crystal structure consists of discrete heptanuclear complexes which are linked by weak intermolecular C-H⋯Cl hydrogen bonds to form a two-dimensional network. In each complex, a central Fe atom is connected to six surrounding Fe centres by alkoxo-type O atoms from the organic ligand. Bond-valence sum calculations indicate that the central Fe ion is FeII, as are two of the outer Fe centers, while the remaining four Fe centers are FeIII. Although the outer Fe atoms are crystallographically equivalent, it is uncertain whether this arises from positional disorder or cha..
