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