A TTF‐based (TTF=tetrathiafulvalene) tridentate ligand (α‐(4′‐methyl‐4,5‐di ‐n ‐dodecylthylthiotetrathiafulvalene‐5′‐ylthio)‐ α ′‐[2,2,2‐tris(1‐pyrazolyl)ethoxy]‐ p ‐xylene) ( L ) with long‐chain alkyl moieties was prepared in order to obtain a new multi‐redox active gelator based on a mixed‐metal octanuclear complex [Fe III 4 Ni II 4 (CN) 12 (tp) 4 (L) 4 ](BF 4 ) 4 ( 1 ). The magnetism, electrochemistry, and gelation behavior of 1 were studied and 1,2‐dichlorobenzene solutions of 1 are shown to display thermoreversible gelation behavior at room temperature. Furthermore, the gel phase of 1 was shown to undergo room‐temperature gel‐to‐sol transformations induced by both the oxidation and reduction of the gelator complex by F 4 TCNQ or [Fe II (Cp*) 2 ], respectively.
