Complexes to toy with : Ring‐closing metathesis of the bis(phosphane) complexes 1 a – c ( n =4–6) followed by hydrogenation gives the “molecular gyroscopes” 2 a – c . The crystal structure of 2 c and the NMR data for the analogous {Fe(CO) 2 (NO)} + complex indicate facile rotation of the {Fe(CO) 2 (L)} m + moieties within the P(CH 2 ) 14 P spokes. Shorter bridges as in 2 a lock the rotators.
