Abstract

The molecular structures of two crown ether adducts of heavier alkali metal derivatives (M = K or Rb) of the primary phosphane “supermesitylphosphane” [i.e. H2PC6H2-t-Bu3-2,4,6] have been determined. The complexes [M{P(H)C6H2-t-Bu3-2,4,6}(18-crown-6)] [M = K 1 or Rb 2] were obtained in good yield by crystallization of MP(H)C6H2-t-Bu3-2,4,6 from toluene–18-crown-6. A main feature is the crown ether adducts of bent MP(H)C6H2-t-Bu3-2,4,6 moieties, thereby representing rare examples of monomeric complexes of the heavier alkali metals containing a phosphide ligand. Both solution and solid-state NMR data are presented.
