A notable feature of the structure of the title compound, C 5 H 6 N 4 O 5 , is the presence of four crystallographically independent and essentially planar but otherwise unremarkable molecules in the asymmetric unit. The molecules are distributed as two pairs which differ in conformation from one pa

The title compound, C 9 H 10 O 5 S, crystallizes with two independent molecules in the asymmetric unit. Hydrogen bonding between these planar molecules gives rise to dimeric species, which produce a crystal structure composed of sheets, stacked parallel to the c axis.
In the paper by Fun, Wang, Xu, Li & Zhang [Acta Cryst. (2003), E59, o1827±o1829], two errors are corrected. First, in the second paragraph of the Comment, `C8ÐC13' on line 6 should read `C2ÐC13'. Secondly, in the third paragraph of the Comment, `the O3/C11/N2/C13 plane' on line 4 should read `the C1
