The reaction of YCl 3 with 2 or 3 equiv. of NaC 5 H 4 CH([CH 2 ] 2 ) 2 NMe in toluene affords [{Y[η‐C 5 H 4 CH([CH 2 ] 2 ) 2 NMe] 2 (μ‐Cl)} 2 ] ( 1 ) and [Y{η‐C 5 H 4 CH([CH 2 ] 2 ) 2 NMe} 3 ] ( 2 ), respectively, in high yield; the three amino‐functionalised cyclopentadienyl units of 2 are fluxional at room temperature, giving us a rare example of stabilisation of an yttrium centre without the use of extraneous ligands.
