The coordination and functionalization of white phosphorus (P) by transition metal and main group element compounds have led to a great variety of polyphosphides. However, larger polyphosphides of the rare-earth elements are elusive. In this study, we report the synthesis and full characterization of the largest polyphosphides of the f-elements, [K(18-crown-6)][(Cp''Ln)(μ-ƞ:ƞ:ƞ:ƞP)], which was isolated along with [K(18-crown-6)][(Cp''Ln)(μ-ƞ:ƞP)] (Ln = La, Ce, Cp'' = 1,3-bis(trimethylsilyl)cyclopentadienyl). These compounds were obtained by using nonclassical divalent compounds of the early lanthanides for the reduction of white phosphorus.
过渡金属和主族元素化合物对白磷（P）的配位和功能化已产生了各种各样的多磷化物。然而，稀土元素的更大的多磷化物却难以捉摸。在本研究中，我们报告了f元素最大的多磷化物[K(18-冠-6)][(Cp''Ln)(μ-ƞ:ƞ:ƞ:ƞP)]的合成与全面表征，该化合物与[K(18-冠-6)][(Cp''Ln)(μ-ƞ:ƞP)]（Ln = La、Ce，Cp'' = 1,3-双（三甲基硅基）环戊二烯基）一同被分离出来。这些化合物是通过使用早期镧系元素的非经典二价化合物还原白磷而得到的。
