A New Class of Metal–Imido Complex : Octahedral hexatantalum clusters [(ArN) 14 Ta 6 O] (see picture; C gray, N blue, O red, Ta orange, Ar=Ph) were formed in good yields by treatment of [Bn 3 TaN t Bu] (Bn=benzyl) or [Ta(NMe 2 ) 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 17 O/ 18 O‐enriched material.
