✦ Synopsis
The iron dibydride FeH,(PP,) [ PP3 = P(CH,CH,CH,PMe,),] is fluctional, with the terminal coordinated phosphine groups undergoing intramolecular exchange in addition to the iron-bound hydrides. Tbe exchange kinetics of the metal-hound hydrides was examined using a magnetization inversio~~ansfer-t.ecovery method, and the activation energy was cu. 64 kJ mot-' at 260 K. The effect of spin-spin coupling on the magnetization trarrsfer was examined.
