. With the attempt to synthesize Nb‐enclosed germanium Zintl cluster ion in ethylenediamine ( en ) / toluene solution, the reaction of K 4 Ge 9 /Na 4 Ge 9 with Nb( mes ) 2 ( mes = mesitylene) gives unexpected 18‐crown‐6 cleavage product of [K 14 Na 2 (NbO 2 ) 2 (C 8 H 16 O 5 ) 8 ](Ge 5 ) ( en ) · solv in the form of very air‐sensitive, light‐brown, plate‐like crystals. This unique compound crystallizes in monoclinic Pn (No. 7) space group, the cleavage of crown linked the 14 potassium, 2 sodium, and 2 niobium atoms into the bulky 2+ charged cation, which balances the [Ge 5 ] 2– anion. This compound represents the rare example of heteronuclear metal alkoxide / Zintl ion hybrid.
