Abstract:
An interesting case of 'halogen-bonding-promoted' crystal structure architecture is presented. The two title compounds, C8H8Br2O2 and C8H8I2O2, have almost indistinguishable mol-ecular structures but very different spatial organization, and this is mainly due to differences in the halogen-bonding inter-actions in which the different species present, i.e. Br and I, take part. The dibromo structure exhibits a π-bonded columnar array involving all four independent mol-ecules in the asymmetric unit, with inter-columnar inter-actions governed by C - Br⋯Br - C links and with no C - Br⋯O/N inter-actions present. In the diiodo structure, instead, the C - I⋯O synthon prevails, defining linear chains, in turn inter-linked by C - I⋯I - C inter-actions. © 2008 International Union of Crystallography.
