A comprehensive review of structurally characterized rare-earth metal complexes containing anionic phosphorus ligands is presented. Since rare-earth elements form hard ions and phosphorus is considered as a soft ligand, the rare-earth metal phosphorus coordination is regarded as a less favorite combination. Three classes of phosphorus ligands, (1) the monoanionic organophosphide ligands (PR2(-)) bearing one negative charge on the phosphorus atom; (2) the dianionic phosphinidene (PR(2-)) and P(3-) ligands; and (3) the pure inorganic polyphosphide ligands (Pn(x-)), are included here. Particular attention has been paid to the synthesis, structure, and reactivity of the rare-earth metal phosphides.
本文全面综述了结构明确的含磷配体的稀土金属配合物。由于稀土元素形成硬离子，而磷被认为是软配体，因此稀土金属磷配位被认为是不太理想的组合。文中包含三类磷配体：(1)磷原子带有一个负电荷的单价有机膦化物配体(PR2(-))；(2)二价磷化物(PR(2-))和 P(3-)配体；和(3)纯无机多磷化物配体(Pn(x-))。本文特别关注了稀土金属磷化物的合成、结构和反应性。
