title: Isomorphous dichloro- and dibromo(2-methyl-2-phenylpropyl)phenylstannane, both displaying the same intramolecular pi-pi interaction at 120 K.
abstract: The title compounds, dichloro- and dibromoneophylphenyltin, [SnCl(2)(C(6)H(5))(C(10)H(13))] and [SnBr(2)(C(6)H(5))(C(10)H(13))], respectively, are remarkable for the 'U' shape of the molecules, whereby the two phenyl groups are brought face-to-face in an arrangement that permits intermolecular C-H.pi bonds to connect the molecules into layers parallel to (100). Intermolecular Sn-halide bonds are notably absent from the structures.
