Bistability of CoⅢ(N-N)(3,6-DBSQ)(3,6-DBCat): Subtle Diimine Ligand Effect (N-N=4,7-Dimethyl-1,10-phenanthroline, 5-Chloro-1,10-phenanthroline; DBSQ = Di-tert-butylsemiquinonato; DBCat = Di-tert-butylcatecholato)

Studies of Co(N-N)(3,6-DBSQ)(3,6-DBCat)(N-N=4,7-dimethyl-1 ,10-phenanthroline, 5-chloro-1,10-phenanthroline; DBSQ=di-tert-butylsemiquinonato; DBCat=di-tert-butylcatecholato) have been carried out on the bistability by intramolecular cobalt-quinone electron transfer in solid state. The title complexes dominantly exist as CdⅢ (N-N)(3,6-DBSQ)(3,6-DBCat) at room temperature and display a significant bistability on temperature variation. Subtle change in optical spectra and magnetic properties is observed when diimine ligands are changed.
