The light-induced excited spin state trapping effect on Ni(dMit)2 salt with an Fe(III) spin-crossover cation:: [Fe(qsal)2][Ni(dmit)2]•2CH3CN

The Ni(dmit)(2) salt with an Fe(III) spin-crossover cation, Fe(qsal)(2), was prepared and showed a cooperative spin transition based on pi-pi interactions between pi-ligands. The light-induced excited spin state trapping effect on this complex was also observed.
