CRYSTAL AND MOLECULAR-STRUCTURE OF (BZLME(3)N)(2)(-)() [FE2OCL6](2)

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.
