Abstract

Reactions of NH4PF6 with BunLi in toluene containing hmpa or pmdeta afford the complexes [Li2-(hmpa)5]2+·2(PF6) - 1, an ion-separated species containing an unusual dinuclear dication, and [(pmdeta)LiPF6]2 2 in which PF6- anions bridge (pmdeta)Li+ units via Li⋯F interactions, this being the first observation of a bridging mode for this anion; ab initio MO calculations help explain the very different structures of 1 and 2.
