Abstract

In the title compound (r.m.s. deviation for the non-H atoms = 0.020 Å), C(10)H(6)Br(2)O(2), an intra-molecular O-H⋯O hydrogen bond generates an S(6) ring. In the crystal, the same H atom also forms an inter-molecular O-H⋯O hydrogen bond, generating a C(2) chain propagating in [100]. The other O-H hydrogen forms a weak O-H⋯π inter-action, and short Br⋯Br contacts [3.5972 (9) Å] also occur.
