The compound [K(18‐crown‐6)] 8 [Ge 9 =Ge 9 =Ge 9 =Ge 9 ] ˙ 8en ( 1 ) featuring a [Ge 9 =Ge 9 =Ge 9 =Ge 9 ] 8‐ cluster anion was synthesized from K 4 Ge 9 for the first time. The X‐ray single crystal analysis shows that, in many respects such as bond connection and packing style, compound 1 is quite different from the previously reported compounds [Rb(18‐crown‐6)] 8 [Ge 9 =Ge 9 =Ge 9 =Ge 9 ] ˙ 2en ( 2 ) and [Rb(18‐crown‐6)] 8 [Ge 9 =Ge 9 =Ge 9 =Ge 9 ] ˙ 6en ( 3 ). Crystal packing of 1 gives strong indications that the highly charged nano‐rods self assembly in a hexagonal rod packing.
