• To introduce halogen-bond interactions between a cation and an anion, a novel Fe super(III) complex from iodine-substituted ligands involving a paramagnetic nickel dithiolene anion was prepared and characterized. The compound exhibited the synergy between a spin-crossover transition and a spin-Peierls-like singlet formation. The halogen-bond interactions between the iodine and the sulfur atoms stabilized the paramagnetic state of pi -spins and played a crucial role in the synergistic magnetic transition between d- and pi -spins. In addition, the compound showed the light-induced excited spin state trapping effect. Something to get crossover: An Fe super(III) complex with iodine-substituted ligands involving a paramagnetic nickel dithiolene anion shows a synergy between a spin-crossover transition and a spin-Peierls-like singlet formation. The halogen-bond interactions between the iodine and the sulfur atoms stabilized the paramagnetic state of pi -spins and played a significant role in the synergistic magnetic transition between d- and pi -spins.
