The Ising on the cake : The cyanide‐bridged low‐spin Fe III –high‐spin Co II compounds of formula [{FeL(CN) 4 } 2 Co(H 2 O) 2 ]⋅4 H 2 O with L=2,2′‐bipyridine (bpy; see picture; O w =water O‐atom) or 1,10‐phenanthroline are 1D Ising systems and the first examples of ferromagnetically coupled bimetallic chains which show slow magnetic relaxation and hysteresis effects. The compounds, therefore, behave as magnetic nanowires.
