Abstract
In the title compound, C(10)H(9)NO(5)S, the fused ring system and the planar (r.m.s. deviation = 0.0037 Å) methoxy-carbonyl-methyl side chain form a dihedral angle of 84.67 (10)°. The crystal structure is stabilized by inter-molecular C-H⋯O hydrogen bonds. A triclinic polymorph of the title compound is already known [Siddiqui et al. (2008 ▶). Acta Cryst. E64, o859].
摘要
在标题化合物C(10)H(9)NO(5)S中，稠环体系与平面（均方根偏差 = 0.0037 Å）甲氧基羰基甲基侧链形成84.67 (10)°的二面角。晶体结构通过分子间C—H⋯O氢键得以稳定。该标题化合物的一种三斜多晶型物已为人所知 [西迪基等人（2008年）。《晶体学报》E辑，64卷，o859]。
