Crown Ether Supported Alkali Metal Phosphides: Synthesis, Structures and Bonding.

ABSTRACT: Herein we present the synthesis and full characterization of the previously unpresented lithium diphenyl phosphides Li(15-crown-5)PPh₂ (1^Li) and Li(12-crown-4)PPh₂ (2^Li) as well as the heavy homologues Rb(18-crown-6)PPh₂ (1^Rb) and Cs(18-crown-6)PPh₂ (1^Cs). We thus complete the series of crown ether coordinated alkali metal diphenyl phosphides and reveal that the structural diversity increases upon descending the group. Including the previously reported Na and K derivatives, we performed a detailed study of the title compounds in solution that strongly indicated all of them are monomers with an alkali metal phosphide AM-P interaction. We further investigated the influence of the phosphorus-bound substitu
