The reaction of [(HN 3 N)ReOCl] ( 1 ) that contains the unsymmetric tren‐based ligand HN 3 N = ({C 6 F 5 NCH 2 CH 2 } 2 NCH 2 CH 2 CH 2 NHC 6 F 5 ) 2− with samarium diiodide leads to the formation of the iodide compounds [(N 3 N)ReI] ( 2 ) and [(HN 3 N)ReOI] ( 3 ). The reduction reaction also generates the unusual rhenium(IV) compound [(HN 3 N*)ReX] ( 4 , X = 0.35 % F and 0.65 % I,), where the amine ligand HN 3 N* = ({C 6 F 5 NCH 2 CH 2 } 2 NCH 2 CH 2 CH 2 NHC 6 F 4 ) 3− is involved in an intramolecular C‐F bond activation. The larger 6‐membered metallacycle formed by the propylene amido substituent facilitates ortho metallation. All compounds have been characterized by single crystal X‐ray analyses.
