Crystal structure of 1-(5-bromo-1-benzofuran-2-yl)ethanone oxime

The title compound, C10H8BrNO2, is almost planar (r.m.s. deviation for the non-H atoms = 0.031 Å) and the conformation across the C=N bond is trans. Further, the O atom of the benzofuran ring is syn to the N atom of the oxime group. In the crystal, inversion dimers linked by pairs of O—H...N hydroge...

Description
Summary:The title compound, C10H8BrNO2, is almost planar (r.m.s. deviation for the non-H atoms = 0.031 Å) and the conformation across the C=N bond is trans. Further, the O atom of the benzofuran ring is syn to the N atom of the oxime group. In the crystal, inversion dimers linked by pairs of O—H...N hydrogen bonds generate R22(6) loops. Very weak aromatic π–π stacking interactions [centroid–centroid separations = 3.9100 (12) and 3.9447 (12) Å] are also observed.
