Abstract

Postsynthesis of the paramagnetic square-shaped complex {[(Tp*^Me)Fe(μ-CN)₂(CN)][Co(dmbpy)₂]}₂ (BPh₄)₂·6MeCN·H₂O [1, Tp*^Me = tris(3,4,5-trimethylpyrazole)-borate; dmbpy = 4,4′-dimethyl-2,2′-bipyr-idine)] 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,LS-Co^III,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.
