Anhydrous lanthanide trichlorides react with N-silylated sodium benzamidinates, Na, (1a-d), to give the monomeric, homoleptic lanthanide(III) benzamidinates 3Ln (2-23, R = H, MeO, CF3, Ph).The molecular structure of 3Pr (11) has been determined by X-ray diffraction.Absorption and emission measurements reveal that the three benzamidinate ligands produce an unusually large crystal field which is comparable with that of cyclopentadienyl. Key Words: Lanthanides / Benzamidinate ligands / Steric cyclopentadienyl equivalents
