title: Bis(1,3-dibenzyl-imidazolium) μ-oxido-bis-[trichloridoferrate(III)].
abstract: In the title compound (C(17)H(17)N(2))(2)[Fe(2)Cl(6)O], obtained from the solid-state reaction of FeCl(2) and N,N'-dibenzyl-imidazolium chloride, the complex anion has approximate D(3d) symmetry with crystallographically imposed inversion symmetry coincident with the bridging μ-O atom. The stereochemistry about each FeCl(3)O centre is distorted tetra-hedral [Fe-Cl = 2.2176 (5)-2.2427 (5) Å and Fe-O = 1.7545 (2) Å]. The Cl atoms are involved in weak anion-cation C-H⋯Cl inter-actions, giving a network structure.
