Synthesis of Molecular Organo‐f‐Element‐Polyphosphides with Nonclassical Divalent Lanthanide Precursors
The coordination and functionalization of white phosphorus (P<sub>4</sub>) 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)]<sub>2</sub>[(Cp''<sub>2</sub>Ln)<sub>2</sub>(μ<sub>4</sub>-ƞ<sup>2</sup>:ƞ<sup>2</sup>:ƞ<sup>2</sup>:ƞ<sup>2</sup>P<sub>14</sub>)], which was isolated along with [K(18-crown-6)][(Cp''<sub>2</sub>Ln)<sub>2</sub>(μ-ƞ<sup>3</sup>:ƞ<sup>3</sup>P<sub>3</sub>)] (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.
