Here, a new bulky silazido ligand, –N(SiHMe2)Dipp (Dipp = C6H3-2,6-iPr2) supports planar, three-coordinate homoleptic rare earth complexes Ln{N(SiHMe2)Dipp}3 (Ln = Sc, Y, Lu) that each contain three secondary Ln←HSi interactions and one agostic CH bond. Y{N(SiHMe2)Dipp}3 and acetophenone react via hydrosilylation, rather than by insertion into the Y–N bond or enolate formation.
