The absolute configuration of the title compound, C16H23BrCl2, has been deduced from the chemical pathway and fully confirmed by refinement of the Flack and Hooft parameters. The six-membered ring adopts a half-chair conformation, whereas the seven-membered ring is a twisted chair. The mol-ecular packing within the crystal is stabilized only by van der Waals inter-actions.
标题化合物C₁₆H₂₃BrCl₂的绝对构型已通过化学途径推导得出，并通过对弗拉克（Flack）和胡夫特（Hooft）参数的精修得到了充分证实。六元环呈半椅式构象，而七元环为扭船式构象。晶体中的分子堆积仅通过范德华相互作用得以稳定。
