Abstract

The asymmetric unit of the title compound, C12H18F4Si2, contains two independent mol­ecules, both lying on inversion centers. The Carene—Si distances are significantly longer than in the analogous non-fluorinated compound. The packing of the mol­ecules results in a herringbone motif in the ac plane.
