摘要
The 2.2.2-cryptand ligand (crypt) that is heavily used in reductions of rare-earth metal complexes to encapsulate alkali metals has been found to function as a bidentate ligand to rare-earth metal ions in some cases. The X-ray crystal structures of the reduced dinitrogen metal complex, [{(R2N)(2)Ce(crypt-kappa(2)-O,O ')}(2)(mu-eta(2):eta(2)-N-2)] (R = SiMe3), and the ytterbium metallocene, (C5Me5)(2)Yb(crypt-kappa(2)-O,O '), are presented to demonstrate this binding mode. The implications of this available binding mode in rare-earth metal cryptand chemistry are discussed.
