ABSTRACT
In the title compound, C5H4BrNO, there are two mol-ecules in the asymmetric unit that are related by a pseudo-inversion center. The two independent mol-ecules are approximately planar, with an observed (ring-ring) angle of 5.49â (13)°. The crystal structure exhibits a herringbone pattern with the zigzag running along the b-axis direction. The least-squares plane containing the rings of both asymmetric molecules and the plane containing the symmetrically related mol-ecules make a plane-plane angle of 66.69â (10)°, which makes the bend of the herringbone pattern. The bromo group on one mol-ecule points to the bromo group on the neighboring mol-ecule, with a Brâ¯Br inter-molecular distance of 4.0408â (16)â Å. The herringbone layer-to-layer distance is 3.431â (4)â Å with a shift of 1.742â (7)â Å. There are no short contacts, hydrogen bonds, or π-π inter-actions.
