Magnetic and photochromic behaviors of cobalt-iron polycyanide (Na0.34Co1.33Fe(CN)6·4.5H2O) were investigated. This compound changes its spin state via photo-induced charge transfer between a low spin state of FeII(S = 0)-CN-CoIII(S = 0) and a high spin state of FeIII(S = 1/2 )-CN-CoII(S = 3/2). The spin transition is accompanied by a color change, indicating a potential application for novel photochromic material.
