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 - intermolecular interaction. Diphenylethyne lies on a crystallographic inversion centre. The structure can be represented as centrosymmetric trimolecular units, held together by a C-Hring interaction between a stilbene and each of the phenyl groups of the diphenylethyne (HCg_ring 2.66 Å; Cg_ring indicates a ring centroid).
