Thermal investigation of bis(methoxy-β-diketonates) of copper(II) — novel CVD precursors of copper films. Crystal structure of bis(2,2,6,8-tetramethyl-6-methoxynonan-3,5-dionato)copper(II)

A combined experimental and computational investigation on Tetrakis-μ-acetato-bis(acetamido)dicopper(II) and its application as a single source precursor for copper oxide

“…In this context, several copper(I) and (II) complexes have been used as copper molecular sources. Nevertheless, despite several works in the field, there is still the demand for novel CVD copper source reagents possessing the combined advantages of Cu(I) and Cu(II) compounds, namely the high thermal stability, appreciable volatility at moderate temperatures, long shelf-life in air, and possibly the capacity of depositing Cu(0) in the absence of reducing gases [9][10][11].Herein, we wish to report on the preparation and characterization of tetrakis-μ-acetato-bis(acetamido)dicopper(II) [Cu(O 2 CCH 3 ) 2 (CH 3-CONH 2 )] 2 (1). Particular attention is also devoted to highlighting the complex thermal properties by the use of thermal analyses technique, in view of eventual CVD applications.…”
