Three new homoleptic lanthanide(III) tris(pivalamidinates), [ t BuC(N i Pr) 2 ] 3 Ln ( Ln = Ce ( 1 ), Eu ( 2 ), Tb ( 3 )) were synthesized by reaction of anhydrous Ln Cl 3 with 3 equivalents of in situ prepared Li[ t BuC(N i Pr) 2 ] in THF. X‐ray structural analyses confirmed the presence of homoleptic, unsolvated tris(amidinates) in which the central Ln 3+ ions are coordinated by three chelating pivalamidinate anions in a distorted all‐nitrogen trigonal prismatic arrangement. Compounds 1 – 3 all crystallize in the monoclinic system, with 1 and 3 containing solvent of crystallization ( 1 : toluene, 3 : n ‐pentane) whereas the europium derivative 2 is unsolvated.
