The direct reduction of main group metals with alkali metals in liquid ammonia almost seventy years ago got E. Zintl on the trail of the polyanions that were later named after him. The cyclo-Sbmath image ion in the title compound (structure of the [Li2(NH3)2Sb5]3− ion depicted on the right demonstrates that the now feasible structure determination of the unstable ammoniates that are obtained from these solutions may still yield some surprises.
