Tri-μ-chlorido-bis­[(η(6)-hexa­methyl­benzene)­ruthenium(II)] tetra­chlorido­ferrate(III)

The mol­ecular geometry of the complex cation in the title structure, [(μ-Cl)(3){Ru(II)(η(6)-C(6)Me(6))}(2)][Fe(III)Cl(4)], compares very well with that reported earlier for the corresponding PF(6) (−) salt [Pandey et al. (1999 ▶). J. Organomet. Chem. 592, 278–282]. The [FeCl(4)](−) counter ion has a rather regular tetra­hedral geometry with Fe—Cl distances and Cl—Fe—Cl angles in the range 2.1891 (7)–2.2018 (8) Å and 107.10 (3)–110.56 (3)°, respectively. There are no significant inter­molecular inter­actions in the crystal except for some weak C—H⋯Cl contacts, which in turn indicates that the crystal packing is determined predominantly by electrostatic inter­actions between the ionic constituents.
