In the article by Dong et al. (2013), the space group was given incorrectly. The crystal belonged to the monoclinic space group P21 instead of the orthorhombic space group P212121. In Table 1, the average multiplicity should be 4.0 (3.2) instead of 2.1 (1.8); the number of unique reflections should be 22686 (1159) instead of 26108; and the total number of reflections should be 90744 (3709) instead of 435550.
