Abstract

Compound [K(18-crown-6)]₂K₂Pb₉ (en)_1.5 (1) was crystallized from the reaction mixture that resulted from adding of an ethylenediamine (en) solution of GeI₂/K to an en solution of K₄Pb₉. The vice versa addition of an en solution of K₄Pb₉ to an en solution of GeI₂/K only lead to the decomposition of the cluster. The single crystal X-ray structure determination shows that compound 1 contains a two-dimensional arrangement _∞²[K₄ Pb₉] of lead Zintl ions. The layers, which have the same composition as the starting material Zintl-Phase K₄Pb₉, are separated by 18-crown-6 molecules.
