In the title com-pound, CHNOS, the S atom is attached equatorially to the sugar ring. The C-S bond lengths are unequal, with S-C = 1.8018 (13) Å and S-C = 1.7662 (13) Å (s = sugar and p = pyrimid-yl). In the crystal, a system of three weak hydrogen bonds, sharing an oxygen acceptor, links the mol-ecules to form chains propagating parallel to the -axis direction.
在标题化合物CHNOS中，S原子以赤道面方式连接到糖环上。C-S键长不相等，S-C = 1.8018 (13) Å且S-C = 1.7662 (13) Å（s = 糖，p = 嘧啶基）。在晶体中，一个由三个共享一个氧受体的弱氢键组成的体系将分子连接起来，形成平行于c轴方向延伸的链。
