Single molecules of the iron(II) complex Fe(bpz)2phen (phen=1,10-phenanthroline, bpz=dihydrobis(pyrazolyl)borate) are reversibly switched between low spin and high spin by electron-induced spin crossover (ELIESST) in a bilayer on gold, as revealed by STM.
Gopakumar et al. (2012) studied this question.
