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.
