Lanthanide complexes containing four-membered N-C-N-Ln, N-S-N-Ln and N-P-N-Ln rings have been synthesized by treatment of lanthanide halides with bulky anionic chelating ligands.Similar ring systems containing four different elements (N-Si-O-Ln) have been obtained by reacting anhydrous lanthanide trichlorides with LitBu)(NtBu)>.A twelve-membered inorganic ring is formed during the reaction of Cp*2Sm(THF)2 with 2.

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
