3,6-Dibromophenanthrene

R. Yokota, C. Kitamura and T. Kawase

Abstract: The phenanthrene ring in the title compound, C14H8Br2, is approximately planar [maximum deviation = 0.039 (3) Å]. In contrast, the two bromo atoms are displaced slightly from the phenanthrene plane [maximum deviation = 0.1637 (3) Å]. In the crystal, the molecules adopt a herringbone-like arrangement and form face-to-face slipped [pi]-[pi] stacking interactions along the b axis, with an interplanar distance of 3.544 (3) Å and slippage of 1.81 Å. The crystal studied was a racemic twin with a minor twin fraction of 0.390 (10).
