(3,6-Dibromo-o-phenylene)dimethanol

The title compound, C8H8Br2O2, was synthesized from the hydrolysis of 1,4-dibromo-2,3-bis(bromomethyl)benzene. One intramolecular O—H⋯O and two intramolecular C—H⋯Br interactions occur. In the crystal, molecules are linked into a chain running parallel to [010]. Adjacent chains are linked into a two-dimensional layer by a combination of intermolecular O—H⋯O hydrogen bonds and C—H⋯π interactions.

The title compound, C 8 H 8 Br 2 O 2 , was synthesized from the hydrolysis of 1,4-dibromo-2,3-bis(bromomethyl)benzene. One intramolecular O-HÁ Á ÁO and two intramolecular C-HÁ Á ÁBr interactions occur. In the crystal, molecules are linked into a chain running parallel to [010]. Adjacent chains are linked into a two-dimensional layer by a combination of intermolecular O-HÁ Á ÁO hydrogen bonds and C-HÁ Á Á interactions.

Experimental
The title compound was synthesized according to the reported literature (Abad et al., 2005 andLai et al., 1993).
Crystals suitable for X-ray diffraction were grown by slow evaporation of a chloroform-methanol (5:1) solution of the title compound at room temperature.

Refinement
All carbon H atoms were placed at their idealized positions with C-H = 0.93 Å (aromatic), 0.97 Å (methylene)) and U iso (H) =1.2 U eq (C) (aromatic and methylene). Hydrogen atoms bonded oxygen atoms were located from the Fourier difference maps and refined with the restraints of O-H=0.82 (1) Å and U iso (H) =1.5 U eq (O). Fig. 1 Refinement. Refinement of F 2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F 2 , conventional R-factors R are based on F, with F set to zero for negative F 2 . The threshold expression of F 2 > σ(F 2 ) is used only for calculating Rfactors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F 2 are statistically about twice as large as those based on F, and R-factors based on ALL data will be even larger.
