Keywords: | single-crystal X-ray study; T = 293 K; mean (C–C) = 0.004 A°; R factor = 0.023; wR factor = 0.055; data-to-parameter ratio = 23.7 | Issue Date: | 31-Mar-2010 | Publisher: | International Union of Crystallography | Project: | SFRH/BD/38387/2008 | Serial title, monograph or event: | Acta Crystallographica Section E: Structure Reports Online | Volume: | 66 | Issue: | Pt 4 | Abstract: | In the title compound, C(12)H(10)I(2)O(4), the meth-oxy groups are twisted considerably with respect to the plane of the aromatic ring [CH(3)-O-C-C torsion angles = -85.9 (3) and -92.8 (3)°]. In the crystal, mol-ecules are linked by weak C-H⋯O hydrogen bonds and O⋯I contacts [3.194 (2) Å]. | URI: | https://hdl.handle.net/10316/110153 | ISSN: | 1600-5368 | DOI: | 10.1107/S1600536810011360 | Rights: | openAccess |
