Abstract

Single crystals of the title compound, C(10)H(11)NO(4), an inter-mediate in the industrial synthesis of yellow azo pigments, were obtained from the industrial production. The mol-ecules crystallize as centrosymmetic dimers connected by two symmetry-related N-H⋯O=C hydrogen bonds. Each mol-ecule also contains an intra-molecular N-H⋯O=C hydrogen bond. The dimers form stacks along the a-axis direction. Neighbouring stacks are arranged into a herringbone structure.

摘要

标题化合物C(10)H(11)NO(4)是黄色偶氮颜料工业合成中的一种中间体，其单晶是从工业生产中获得的。分子以中心对称二聚体的形式结晶，通过两个对称相关的N-H⋯O=C氢键相连。每个分子还含有一个分子内N-H⋯O=C氢键。二聚体沿a轴方向形成堆叠。相邻的堆叠排列成鱼骨结构。
