Crystal Structure of “[Li(Et2O)]4[FePh4]”: Corrigendum and Reformulation. A Remarkable Example of a False Solution in a Wrong Space Group
نویسندگان
چکیده
The crystal structure of the supposed tetraphenylferrate(0) salt “[Li(Et2O)]4[FePh4]” reported by Shilov et al. has been reinterpreted, and the unprecedented “flat rectangular” coordination geometry is proposed to be an artifact of a false solution in an incorrect space group. In the correct space group, the phenyl groups actually describe a regular square-planar geometry with cis C-Fe-C angles that are exactly 90°. In addition, the formulation of the compound as a derivative of zerovalent iron is almost certainly incorrect: we propose that the compound actually is an iron(II) dihydride of stoichiometry [Li(Et2O)]4[trans-FeH2Ph4].
