A Structural Diversity of Molecular Alkaline-Earth-Metal Polyphosphides: From Supramolecular Wheel to Zintl Ion.

ABSTRACT: A series of molecular group 2 polyphosphides has been synthesized by using air-stable [Cp*Fe(η⁵ -P₅ )] (Cp*=C₅ Me₅ ) or white phosphorus as polyphosphorus precursors. Different types of group 2 reagents such as organo-magnesium, mono-valent magnesium, and molecular calcium hydride complexes have been investigated to activate these polyphosphorus sources. The organo-magnesium complex [(^Dipp BDI-Mg(CH₃ ))₂ ] (^Dipp BDI={[2,6-ⁱ Pr₂ C₆ H₃ NCMe]₂ CH}^- ) reacts with [Cp*Fe(η⁵ -P₅ )] to give an unprecedented Mg/Fe-supramolecular wheel. Kinetically controlled activation of [Cp*Fe(η⁵ -P₅ )] by different m
