The solid potassium trimethylsilylcyclopentadienide 1 may be viewed as a “supersandwich” complex . It represents the first base‐free alkali‐metal cyclopentadienide to be obtained in crystalline form. Complex 1 contains parallel‐arranged, one‐dimensional, infinite structural units in which the potassium atoms (black) and the cyclopentadienyl rings (pentahapto‐bonded on both sides) alternate. Weak interactions exist between the strands.
