Is the surface of Hofmann-like spin-crossover {Fe(pz)[Pt(CN)]} the same as its bulk?
Temperature dependent X-ray photoemission spectroscopy (XPS) has been employed to examine the spin-crossover (SCO) transition in the nanocrystals of 3D Hoffman-like {Fe(pz)[Pt(CN) 4 ]}. Consistent with the existing literature, the temperature-dependent variations in the Fe 2p core-level spectrum pro...
