Abstract
The molecular structure of the title compound, C22H38Si2, features a trans arrangement of the cyclopentadienyl rings to avoid steric strain [C—Si—Si—C torsion angle = −179.0 (5)°]. The Si—Si bond length is 2.3444 (4) Å. The most notable intermolecular interactions in the molecular packing are C—H⋯π contacts that lead to the formation of wave-like supramolecular chains along the b axis.
