The novel tricyclic polychalcogenide anions [Sb 2 Se 12 ] 2– and [Te 12 ] 4– were obtained by reduction of elemental selenium and tellurium with Li 3 Sb and subsequent crystallization with the crown ether 12‐crown‐4 in ethylenediamine. According to single‐crystal structure analysis, [Li(12‐crown‐4) 2 ] 2 [Sb 2 Se 12 ] consists of two six‐membered (Se 5 Sb)‐rings that are connected via a central (Sb 2 Se 2 )‐ring. [Li(12‐crown‐4) 2 ] 4 [Te 12 ](12‐crown‐4) 2 contains the tricyclic [Te 12 ] 4– anion, consisting of two four‐membered tellurium rings and a central Te 8 ‐ring. EDX analysis proves that the latter compound does not contain antimony.
