The iron dihydride FeH 2 (PP 3 ) [PP 3 = P(CH 2 CH 2 CH 2 PMe 2 ) 3 ] is fluctional, with the terminal co‐ordinated phos‐phine groups undergoing intramolecular exchange in addition to the iron‐bound hydrides. The exchange kinetics of the metal‐bound hydrides was examined using a magnetization inversion–transfer–recovery method, and the activation energy was ca . 64 kJ mol −1 at 260 K. The effect of spin–spin coupling on the magnetization transfer was examined.
