The crystal and molecular structure of (BzlMe(3)N)(2)(+) [Fe2OCl6](2-)
has been determined. The asymmetric unit contains two benzyltrimethyl
ammonium cations and two half mu-oxo-bis(trichloro-iron(III)) anions.
The bridging mu-oxygen atoms of these anions are located over crystall
ographic symmetry elements. Therefore, the two anions resulting from t
he symmetry operations correspond to two different conformers presenti
ng ''angular'' and ''linear'' dispositions of the Fe-O-Fe bond angle.
Mossbauer spectrum consists of two asymmetric lines that are adequatel
y simulated by two equally populated quadrupole doublets associated wi
th the two iron sites.
