Abstract

The toluene solution structure of an N-lithio(triphenyl)phosphazene (Ph3PNLi) mixed aggregate with lithium bromide (LiBr), 5, has been elucidated for the first time based on multinuclear magnetic resonance measurements (1H, 6Li, 7Li, 13C and 31P). The structure consist of two dimers [Li(μ-Z)]2 (Z= Br, NPR3) linked through LiX (X= N, Br) bridges. This arrangement is a cubane-like structure analogous to that found in the solid-state.
