A highly symmetric structure is displayed in toluene by 1, which was obtained by reduction of octasilyl[4]radialene with lithium in THF. The two Li ions of 1 are not fixed to the ฯ€-electron system in toluene, but are fluxional, giving rise to a bis-contact ion pair. In a solvating medium such as THF
