Ruthenium amidinate

WebMay 27, 2004 · The reaction of the octahedral anilido complex (PCP)Ru(CO)(NHPh)(PMe3) with acetonitrile produces the amidinate complex (PCP)Ru(CO){N(H)C(Me)N(Ph)}. Mechanistic studies indicate that the reaction proceeds through coordination of the nitrile to the Ru(II) metal center, followed by intramolecular nucleophilic addition of the amido ligand. WebOct 11, 2007 · Atomic layer deposition (ALD) and pulsed chemical vapor deposition (CVD) were used to make ruthenium (Ru) thin films from a volatile Ru amidinate precursor, bis ( -di- tert -butylacetamidinato)ruthenium (II) dicarbonyl. The CVD films were grown without any coreactant, while the ALD films used ammonia as a coreactant.

Inorganic Chemistry 2007, 46 (17) , 6958-6967. DOI: 10.1021/ic700674c. WebAmidinate precursors such as Bis(N,N’-di-t-butylacetamidinato)ruthenium(II) dicarbonyl have characteristics that overcome some of these issues. Each amidinate ligand chelates the metal center through two metal-nitrogen bonds. These relatively weak M-N bonds and strong byproduct N-H bonds lead to lower ALD growth temperatures.
