D/f-Polypnictides Derived by Non-Classical Ln²⁺ Compounds: Synthesis, Small Molecule Activation and Optical Properties.

ABSTRACT: Reduction chemistry induced by divalent lanthanides has been primarily focused on samarium so far. In light of the rich physical properties of the lanthanides, this limitation to one element is a drawback. Since molecular divalent compounds of almost all lanthanides have been available for some time, we used one known and two new non-classical reducing agents of the early lanthanides to establish a sophisticated reduction chemistry. As a result, six new d/f-polyphosphides or d/f-polyarsenides, [K(18-crown-6)] [Cp''₂ Ln(E₅ )FeCp*] (Ln=La, Ce, Nd; E=P, As) were obtained. Their reactivity was studied by activation of P₄ , resulting in a selective expansion of the P₅ rings. The obtained compounds [K(18-crown-6)] [Cp''₂ Ln(P₇ )Fe
