Thermally-induced nickelocene fragmentation and one-dimensional chain assembly on Au(111).

ABSTRACT: The ability to control molecular adsorption and transformation on surfaces is key to advancing nanoscale fabrication, catalysis, and quantum materials engineering. Transition-metal metallocenes, such as nickelocene (NiCp₂), offer intriguing opportunities due to their well-defined electronic and magnetic properties, making them ideal candidates for studying surface interactions at the atomic level. We investigate the adsorption and transformation of NiCp₂, a nickel atom coordinated by two cyclopentadienyl (Cp) rings, on a Au(111) surface using scanning tunneling microscopy (STM) and density functional theory (DFT) calculations. At low temperatures, NiCp₂ preferentially adsorbs at herringbone elbows and step edges, forming ordered assemblies. Upon heating, Ni
