cis-1,2-Dibromo-1,2-diphenylethene-diphenylethyne (2/1)

J. C. Barnes and J. A. Chudek

Abstract: The molecular components, 2C14H10Br2·C14H10, are arranged in separate stacks in this ordered structure. There is no evidence of [pi]-[pi] intermolecular interaction. Diphenylethyne lies on a crystallographic inversion centre. The structure can be represented as centrosymmetric trimolecular units, held together by a C-H...ring interaction between a stilbene and each of the phenyl groups of the diphenylethyne (H...Cgring 2.66 Å; Cgring indicates a ring centroid).
