title: 4-Bromo-seleno-anisole.
abstract: The title compound, 1-bromo-4-methyl-seleno-benzene, C(7)H(7)BrSe, was prepared by methyl-ation of 4-bromo-seleno-phenolate with methyl iodide, and crystals suitable for structure determination were obtained by sublimation. The mol-ecule is essentially planar; the Se-Me bond is rotated by only 2.59 (19)° out of the least-squares plane of the benzene ring. The most pronounced intermolecular interactions are two hydrogen bonds of the type C-H⋯π, which determine a herring-bone pattern in the crystal packing.
