A New Class of Metal–Imido Complex: Octahedral hexatantalum clusters [(ArN)14Ta6O] (see picture; C gray, N blue, O red, Ta orange, Ar=Ph) were formed in good yields by treatment of [Bn3Ta[DOUBLE BOND]NtBu] (Bn=benzyl) or [Ta(NMe2)5] with an excess of the appropriate aniline and an equivalent of water. Crystallographic analysis revealed the presence of a central oxygen atom, which was further identified by electrospray mass spectrometry using 17O/18O-enriched material.
