["Postsynthesis of the paramagnetic square-shaped complex {[(Tp*(Me))Fe(mu-CN)(2)(CN)][Co(dmbpy)(2)]}(2)(BPh4)(2)center dot 6MeCN center dot H2O [1, Tp*(Me) = tris(3,4,5-trimethylpyrazole)-borate; dmbpy = 4,4'-dimethyl-2,2'-bipyridine)] by grafting transition metal(II) thiocyanates via its terminal cyano groups afforded three hexanuclear [Fe2Co2M2] clusters (M = Zn, 2; Co, 3; Cd, 4). The peripheral metal-complex units serving as excellent electron acceptors were found to help stabilize the low-temperature state of Fe-II,Fe-LS-Co-III,Co-LS within the complex core. As a result, the desolvated complexes 2-4 underwent reversible and sharp thermally induced electron-transfer behavior with the transition temperatures (T-1/2) up to 312, 296, and 365 K, respectively, demonstrating an effective means of manipulating thermal barriers of the celebrated cyano-bridged square core.","[GRAPHICS]","."]
