Abstract
Magnetic and photochromic behaviors of cobalt-iron polycyanide (Na0.34Co1.3 3Fe(CN)(6). 4.5H(2)O) were investigated. This compound changes its spin sta te via photo-induced charge transfer between a low spin state of Fe-II(S = 0)-CN-Co-III(S = 0) and a high spin state of Fe-III (S = 1/2)-CN-Co-II(S = 3/2). The spin transition is accompanied by a color change, indicating a po tential application for novel photochromic material.
