摘要：

Clean Pt(111) chemisorbs both cis-(CH3)2Pt(CH3NC)2[HPt] and CF3AuCH3NC[FMG]. Ligand-metal bond cleavage occurs even at low temperature, yielding adsorbed CH3NC. Further dissociation of the ligand to H-2 and HCN occurs on heating. On Au, FMG chemisorption again occurs, and desorption of CH3NC is detected, but no H-2 or HCN are formed, consistent with the deposition of pure, C-free Au films. Surface chemistry is completely suppressed on graphitized Pt(111) indicating physisorption of both precursors.
