-Oxo-²O:O-bis[bis(1,10-phenanthroline-²N,N')(sulfato-O)iron(III)] octahydrate

M. Odoko and N. Okabe

Abstract: In the crystal structure of the title binuclear iron(III) complex, [Fe ${}_{2}^{\rm III}$ O(SO₄)₂(C₁₂H₈N₂)₄]·8H₂O, the Fe atoms are connected by an O atom, which lies on a twofold axis. Each Fe atom is also coordinated by four N atoms of two 1,10-phenanthroline ligands and one O atom of a sulfate ion, resulting in a distorted octahedral geometry. The FeFe separation is 3.5552 (21) Å and the Fe-O-Fe bridge angle is 172.81 (12)°. The crystal packing is stabilized by a network of O-HO hydrogen bonds.
