The super‐bulky hydrotris(3‐ tert ‐butyl‐5‐methylpyrazolyl)borato ligand (Tp t Bu,Me ) allows the isolation of the monolanthanide complexes [Tp t Bu,Me Ln{(μ‐H)AlMe 3 } 2 ] (Ln=Y, Lu; see structure), which can be transformed into discrete non‐agglomerated imide complexes [Tp t Bu,Me Ln{(μ‐NC 6 H 3 Me 2 ‐2,6)(μ‐H)AlMe 2 }] by reaction with dimethylaniline. Ln hydrido bonding is corroborated by 1 H NMR spectroscopy through 1 H– 89 Y coupling and 89 Y DEPT45 NMR spectroscopy.
