Communication: Triplet electron‐transfer salts are predicted to exhibit bulk ferromagnetic behavior at higher temperatures than their singlet analogues. To test this expected trend, the title compound, which is isostructural with [FeCp * 2 ] ⊙⊕ [TCNE] ⊙⊖ (Cp * = pentamethylcyloopentadienide; TCNE = tetracyanoethylene) which exhibits a Curie temperature, T c , of 4.8 K has been synthesized. The synthesis and magnetic characterization of the new compound, which is found to have a T c of 8.8 K, are reported.
