In the structure of the title compound, CHNOS, the bond lengths in the C-S-C moiety are almost equal at 1.7959 (8) and 1.7877 (9) Å, with a shorter formally double C-S bond of 1.6698 (9) Å at the other sulfur atom. The eight-atom sequence O3-C3-C2-C1-S-C-N-C (using standard sugar numbering) shows an extended conformation. The packing involves 'weak' hydrogen bonds, whereby the three shortest C-H⋯O contacts combine to form layers of mol-ecules parallel to the plane.
在标题化合物CHNOS的结构中，C-S-C部分的键长几乎相等，分别为1.7959 (8) Å和1.7877 (9) Å，而在另一个硫原子处，形式上的双键C-S键较短，为1.6698 (9) Å。八原子序列O3-C3-C2-C1-S-C-N-C（采用标准糖编号）呈伸展构象。堆积涉及“弱”氢键，其中三个最短的C-H⋯O接触相结合，形成与 平面平行的分子层。
