Aryl-Aryl Interactions in (Aryl-Perhalogenated) 1,2-Diaryldisilanes.

ABSTRACT: Three 1,2-diaryltetramethyldisilanes X₅ C₆ -(SiMe₂ )₂ -C₆ X₅ with two C₆ H₅ , C₆ F₅ , or C₆ Cl₅ groups were studied concerning the importance of London dispersion driven interactions between their aryl groups. They were prepared from 1,2-dichlorotetramethyldisilane by salt elimination. Their structures were determined in the solid state by X-ray diffraction and for free molecules by gas electron-diffraction. The solid-state structures of the fluorinated and chlorinated derivatives are dominated by aryl-aryl interactions. Unexpectedly, Cl₅ C₆ -(SiMe₂ )₂ -C₆ Cl₅ exists exclusively as an eclipsed s
