title: Solution NMR structural study of a mixed aggregate of N-lithium triphenylphosphazene and lithium bromide.
abstract: The toluene solution structure of an N-lithio(triphenyl)phosphazene (Ph(3)PNLi) mixed aggregate with lithium bromide (LiBr), 5, has been elucidated for the first time based on multinuclear magnetic resonance measurements ((1)H, (6)Li, (7)Li, (13)C and (31)P). The structure consist of two dimers [Li(mu-Z)](2) (Z= Br, NPR(3)) linked through LiX (X= N, Br) bridges. This arrangement is a cubane-like structure analogous to that found in the solid-state.
