New Volatile Tantalum Imido Precursors with Carboxamide Ligands.

ABSTRACT: A series of Ta(V) ^t Bu-imido/N-alkoxy carboxamide complexes, TaCl₂(N ^t Bu)(pyridine)(edpa) (1), TaCl(N ^t Bu)(edpa)₂ (2), Ta(N ^t Bu)(edpa)₃ (3), TaCl₂(N ^t Bu)(pyridine)(mdpa) (4), and Ta(N ^t Bu)(mdpa)₃ (5), were successfully synthesized by metathesis reactions between Ta(N ^t Bu)Cl₃(py)₂ and several equivalents of Na(edpa) (edpaH = N-ethoxy-2,2-dimethylpropanamide) and Na(mdpa) (mdpaH = N-methoxy-2,2-dimethylpropanamide). Furthermore, complexes 3 and 5 were simply transformed to new dimeric structures [Ta(μ₂-O)(e
