  The synthesis and structural characterization of new tantalum(V) compounds containing a single hydrazido(1) ligand are reported. Hydrazinolysis of TaCl(NMe2)(4) using trimethylsilyl(dimethyl)hydrazine affords the compound TaCl(NMe2)(3)[N(TMS)NMe2] in essentially quantitative yield. Metathetical replacement of the chloride ligand in TaCl(NMe2)(3)]N(TMS)NMe2] by LiNMe2 gives the all-nitrogen coordinated compound Ta(NMe2)(4)[N(TMS)NMe2]. VT H-1 NMR studies support the existence of low-energy pathways involving rotation about the Ta-N bonds of the ancillary amido and hydrazido ligands in both hydrazido-substituted compounds. X-ray crystallographic analyses confirm the octahedral disposition about the tantalum metal in TaCl(NMe2)(3)[N(TMS)NMe2] and Ta(NMe2)(4)[N(TMS)NMe2] and the presence of an mu(2)-hydrazido(1) ligand. Preliminary data using Ta(NMe2)(4)[N(TMS)NMe2] as an ALD precursor for the preparation of tantalum nitride and tantalum oxide thin films are presented. (C) 2010 Elsevier Ltd. All rights reserved.
