| Abstract: | The ammoniate K17(Sb8)2(NH2)] · 17.5NH3 was synthesized by reduction of antimony with potassium in liquid ammonia. Single crystals were isolated and characterized by low temperature X‐ray structure analysis. K17(Sb8)2(NH2)] · 17.5NH3 crystallizes in the space group P21/c (No. 14) with a = 12.976(1) Å, b = 24.536(1) Å, c = 22.858(1) Å and β = 99.17(1)°. The ammoniate contains crown‐shaped Sb8]8? Zintl anions which are analogous to S8 rings. The presence of amide NH2? as an additional anion is deduced from coordination observations and the close similarity of structural features to the structure of KNH2. |
