In this report we discuss the synthesis of [Fe 2 (CO) 6 {μ‐(TeCH 2 Te)}] ( 2 ) using Fe 3 (CO) 12 and Me 2 Sn(CH 2 I) 2 in the presence of potassium tellurocyanate, freshly prepared. The resulting complex was characterized by different spectroscopic methods ( 1 H, 13 C{ 1 H} and 125 Te{ 1 H} NMR) as well as X‐ray diffraction analysis. Moreover, we investigate the redox properties and the catalytic behavior of 2 in the presence of weak and moderate acids, acetic acid (AcOH) and trifluoracetic acid (TFA), respectively, as a source of protons.
