The molecular structures of hexakis((methylsilylethyl)benzene (6) and the solvent adducts of hexakis(( trimethylsilyl)ethyl)benzene (7 . 2CH(2)Cl(2)) and hexakis(dibenzylmethylsilyl)ethyl)benzene (11 . 2CHCl(3)) have been determined by X-ray diffraction studies. Each dichloromethane and chloroform molecule formed C-H ... aryl hydrogen bonds, one above and one below, to the ring centroid. The distances between the carbon and the ring centroid were 3.469 and 3.466 Angstrom for CH2Cl2 and CHCl3, respectively.
