Abstract:
The title compounds, C10H11ClO3, (I), and C10H11BrO3, (II), are isomorphous and effectively isostructural; all of the interatomic distances and angles are normal. The structures exhibit long intermolecular C-H...O and C-H...pi contacts with attractive energies ranging from 1.17 to 2.30 kJ mol(-1). Weak C-H...O hydrogen bonds form C(3) and C(4) motifs, combining to form a two-dimensional R(3)(4)(12) net. No face-to-face stacking interactions are observed.
