Hexaaquairon(II) bis[fac-tribromidotricarbonylferrate(II)]

In the title compound, [Fe(H2O)(6)][FeBr3(CO)(3)](2), both Fe atoms have an octahedral coordination and the bromide carbonyl complex has a fac-stereochemistry. The [Fe(H2O)(6)](2+) octahedron has point symmetry (1) over bar and is slightly compressed along one O-Fe-O axis. The [FeBr3(CO)(3)](-) anion has point symmetry 1 and mean bond lengths of Fe-Br = 2.455 (5) angstrom and Fe-C = 1.809 (2) angstrom. The cation and anion complexes are mutually linked via O-H center dot center dot center dot Br hydrogen bonds with O center dot center dot center dot Br distances of 3.340 (3) to 3.388 (3) angstrom.
