Abstract

In the title 2:1 co-crystal, 2CHClN·CHO the complete succinic acid mol-ecule is generated by a crystallographic centre of symmetry. In the crystal, pairwise O-H⋯N and N-H⋯O hydrogen bonds link the pyrimidine and succinic acid mol-ecules, generating (8) loops. The pyrimidine mol-ecules are linked by pairwise N-H⋯N hydrogen bonds, again generating (8) loops. Collectively, the hydrogen bonds link the components into corrugated (100) sheets. The Hirshfeld surface is presented.

摘要

在标题为2:1的共晶体2CHClN·CHO中，完整的琥珀酸分子由一个晶体学对称中心产生。在晶体中，成对的O-H⋯N和N-H⋯O氢键连接嘧啶和琥珀酸分子，形成(8)环。嘧啶分子通过成对的N-H⋯N氢键相连，同样形成(8)环。总的来说，氢键将这些组分连接成波纹状的(100)片层。展示了 Hirshfeld 表面。
