Well‐characterized Group 14 Zintl anions were accessible by solution methods only in low yields up to now. An easy and inexpensive reaction route to polyanions, which starts from the elements, is admissible through the usage of [18]crown‐6 as reaction medium at 40°C. The [K([18]crown‐6)] unit proves to be an advantageous connecting device between intermetallic and organic networks. The title compound can be regarded as a supramolecular aggregate of a one‐dimensional substructure of the composition K 4 Sn 9 (see picture) and an organic component.
