Abstract

The compounds Cp₂Ce[η³-N(QPPh₂)₂] (Q = S (1), Se (2)) and Cp₂Ce[η³-N(SPⁱPr₂)(SePPh₂)] (3) have been synthesized from the protonolysis reactions between Cp₃Ce and HN(QPPh₂)₂ or HN(SPⁱPr₂)(SePPh₂) in THF. The structures of these compounds have been determined by X-ray crystallographic methods. The three compounds have similar structures in which the ligands are coordinated to Cp₂Ce moiety in an η³ fashion through the two chalcogen atoms and an N atom. Whereas the ⁷⁷Se NMR resonances are normal the ³¹P NMR resonances are shifted to much lower frequencies than in similar rare-earth compounds.
