A Monometallic Iron(I) Organoferrate

Tetra-<i>n</i>-butylammonium (TBA) (η<sup>6</sup>-biphenyl)­diphenylferrate was formed unexpectedly in the reaction of (TBA)<sub>2</sub>[Fe<sub>4</sub>S<sub>4</sub>Cl<sub>4</sub>] with an excess of phenyllithium. This complex belongs to a novel type of organoferrate.
