✦ Synopsis

The title compound, [Fe 2 (C 14 H 17 NSSi)(CO) 6 ], was produced by the reaction of N-(3-thienylmethylidene)-4-(trimethylsilyl)aniline and Fe 2 (CO) 9 via a reaction sequence involving a CÐH activation step, followed by an intramolecular hydrogen transfer to the former imine C atom. The crystal structure analysis clearly proves that the reaction takes place regioselectively at the 2-position of the thiophene moiety. The structure of the title compound consists of an azaferracyclopentadiene ring to which another Fe(CO) 3 moiety is apically coordinated. There are two independent molecules per asymmetric unit, which differ slightly in their bond lengths and angles.
