摘要：

The complexes Ce(NO3)3(HL)3 (I) and Ce(NO3)3L(HL) (II) have been prepared where HL = Ph2P(O)CH2C(O)Ph. The structure of I has been determined and shows that the cerium atom is ten coordinate. HL is bound as both bidentate and monodentate ligands with the third ligand showing intermediate bonding characteristics. The infrared spectra of the complex are discussed in terms of the observed modes of bonding. The thermally unstable Ce(IV) complex, II, contains the phosphine oxide bound as both neutral and anionic chelates, probably in a ten- coordinate complex. © 1990.
