Abstract

A new trinuclear species containing a Ta(iv)-Ta(iv) bond, Ta ₃(μ-H)(μ-NMe₂)(μNBu^t) ₂(NBu^t)(NMe₂)₅, has been formed by reductive elimination of H₂. Ta₂H₂(μ- NMe₂)₂(NMe₂)₂(NBu^t) ₂ has also been isolated. O₂ oxidizes the Ta(iv)-Ta(iv) bond to yield Ta₃(μ₃-O)(H)(μNBu^t)(μ- NMe₂)₂(NMe₂)₄(NBu^t) ₂ under ligand exchange. Delocalization of d electrons is discussed.
