2-(1-Adamant-yl)-4-bromo-anisole at 123†K.

IN THE TITLE COMPOUND [SYSTEMATIC NAME: 2-(1-adamantyl)-4-bromo-1--methoxy-benzene], C(17)H(21)BrO, two weak intra-molecular C-H⋯O hydrogen bonds influence the mol-ecular conformation. The crystal packing exhibits C-H⋯π inter-actions, with a relatively short inter-molecular C⋯Cg contact of 3.568 (5) Å, where Cg is the centroid of the benzene ring. The crystal studied exhibited inversion twinning.
