Reaction of lanthanoid tris(2, 6‐diphenylphenolates) [Ln(Odpp) 3 ] with KOdpp in 1, 2, 4, 5‐tetramethylbenzene (durene) at 200‐250 °C affords [K{Ln(OC 6 H 3 Ph 2 ‐2, 6) 4 }], (Ln = La ( 1 ) or Nd ( 2 )) and 2 has also been obtained from the reaction of [Nd(Odpp) 3 ] with potassium hydride. In the solid state, 1 and 2 are monomeric bimetallics in which Ln is surrounded by a distorted tetrahedral array of oxygen atoms. Two Odpp ligands are oxygen bridged between K and Ln and also are η 4 ‐Ph linked to potassium. One Odpp ligand bridges the metals in an O(Ln): η 6 ‐Ph(K) manner that is new for lanthanoid complexes of this ligand, with no close K‐O contact, and the remaining Odpp is terminal on the Ln.
