Abstract

The crystal and molecular structures of N-cyano-N'-methyl-N"-(2-[(2-amino-5-thiazolyl) methylthio] ethyl) guanidine and N-cyano-3-[(2-guanidino-5-thiazolyl)methylthio]propionamidine are reported. Both molecules are in an extended conformation. In all two crystals a system of hydrogen bonds links the molecules in a three-dimensional network. A comparison with the structure of cimetidine and famotidine is also included.

摘要

报道了N-氰基-N'-甲基-N"-(2-[(2-氨基-5-噻唑基)甲硫基]乙基)胍和N-氰基-3-[(2-胍基-5-噻唑基)甲硫基]丙脒的晶体结构和分子结构。两个分子均呈伸展构象。在所有两个晶体中,氢键体系将分子连接成三维网络。还包括与西咪替丁和法莫替丁结构的比较。
