This corrigendum is to address an issue regarding the manuscript’s previous publication. The authors have regrettably noticed that the incorrect version of the figure and crystal data was used in the original published version of this paper. To rectify this oversight and ensure the accuracy of the published work, the correct figure and data are included for your reference
A single crystal of 6 was obtained by slow evaporation from MeOH enantiomers that crystallizes in the orthorhombic space group P2_1_2_1_2_1_ with Z = 4. There is one molecule in the asymmetric unit.
X-ray Crystallography
For the crystal structure determination, single-crystal of the compound 2,3,5,8-tetrabromo-4-methoxy-1,2,3,4-tetrahydronaphthalen-1-ol (6) was used for data collection on a Bruker APEX-II CCD diffractometer (equipped with a two-dimensional area CCD detector). Graphite-monochromated Mo-Kα radiation (λ= 0.71073 Å) and oscillation scan technique with Δw = 5° for one image were used for data collection. The lattice parameters were determined by the least-squares methods on the basis of all reflections with F^2^>2σ**(F^2^ ). The integration of the intensities, correction for Lorentz and polarization effects and cell refinement was performed using Bruker SAINT (Bruker AXS Inc., 2012) software ^9^. The structures were solved by direct methods using SHELXS- 97^10^ allowed for the location of most of the heaviest atoms, with the remaining non-hydrogen atoms being located from different Fourier maps calculated from successive full-matrix least squares refinement cycles on F^2^ using SHELXL-97^10^. All non-hydrogen atoms were refined using anisotropic displacement parameters. Hydrogens attached to carbons were located at their geometric positions using appropriate HFIX instructions in SHELXL. The final difference Fourier maps showed no peaks of chemical significance.
