3-N-(3-thienylmethylidene)-4-(trimethylsilyl)aniline]diironAbstract: The title compound, [Fe2(C14H17NSSi)(CO)6], was produced by the reaction of N-(3-thienylmethylidene)-4-(trimethylsilyl)aniline and Fe2(CO)9 via a reaction sequence involving a C-H 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.
