N,N'-Dibutyl-N,N,N',N'-tetra-methyl-ethane-1,2-diaminium μ-oxido-bis-[trichloridoferrate(III)].

The asymmetric unit of the title compound, (C(14)H(34)N(2))[Fe(2)Cl(6)O], contains one complete cation, two half-cations and two anions. The two half-cations are completed by crystallographic inversion symmetry. The Fe(III) atoms adopt fairly regular FeCl(3)O tetra-hedral geometries, although the bridging Fe-O-Fe bond angles differ significantly in the two anions, which both adopt an eclipsed conformation. In the crystal, the components are linked by C-H⋯Cl and C-H⋯O inter-actions.
