Single‐molecule magnets : A cyanide‐bridged hexanuclear complex showed a thermal electron‐transfer‐coupled spin transition centered at 220 K. Light irradiation at low temperature (LT; HT=high temperature) generated a metastable state showing slow magnetic relaxation in measurements of the alternating‐current magnetic susceptibility ( χ m ; see picture).
