The crystal and molecular structure of (BzlMe3N)2+[Fe2OCl6] 2- has been determined. The asymmetric unit contains two benzyltrimethylammonium cations and two half μ-oxo-bis(trichloroiron(III)) anions. The bridging μ-oxygen atoms of these anions are located over crystallographic symmetry elements. Therefore, the two anions resulting from the symmetry operations correspond to two different conformers presenting "angular" and "linear" dispositions of the Fe-O-Fe bond angle. Mössbauer spectrum consists of two asymmetric lines that are adequately simulated by two equally populated quadrupole doublets associated with the two iron sites.
