1,20-Dibromoicosane

N. Nakamura and A. Ohishi

Abstract: The molecule of the title compound, C₂₀H₄₀Br₂, is centrosymmetric and the skeleton has an all-trans conformation including both terminal Br atoms. In the crystal structure, the molecules form a layer in which the long axes of the molecules are inclined to the basal plane of the Br atoms. The layers are arranged in a zigzag manner between the neighboring layers, forming a herringbone motif, just like the smectic C_A phase of liquid crystals.
