The title compound (C10H11BrO4, Mr = 275.10) was synthesized and its crystal structure has been determined by single-crystal X-ray diffraction. The crystal is of monoclinic, space group P21/n with a = 7.2960(8), b = 12.209(1), c = 12.568(1) ? b = 98.120(2)? l = 0.71073 ? m(MoKa) = 3.700 mm-1, V = 1108.3(2) 3, Z = 4, Dc = 1.649 g/cm3 and F(000) = 552. The structure was solved by direct methods and refined by full-matrix least-squares methods. R = 0.0375 and wR = 0.0864 for 1598 reflections with I > 2s(I). X-ray diffraction reveals that there exist two rings in the molecule, and the dihedral between them is 177.5?
