Abstract

Two rare-earth (La and Lu) naphthalene complexes supported by a ferrocene diamide ligand activate P4 under ambient conditions to form M3P7 species exclusively. The resulting complexes feature a Zintl-type polyphosphide P73– unit stabilized by three lanthanide fragments. The reported metal complexes were characterized by X-ray crystallography, multinuclear NMR spectroscopy, and elemental analysis.
