In the title compound, [CHNCONHCHCH]I or CHNO·I, a cation and an anion form an ionic pair linked by a strong N-H⋯I hydrogen bond. In the crystal, ionic pairs linked by weak C-H⋯I hydrogen bonds form infinite ribbons along the crystallographic axis. Polymorphism screening varying crystallization solvents (water, acetone 90%-water, ethanol 90%-water, 2-propanol 90%-water, DMF, DMSO, methanol, aceto-nitrile) and conditions (solution temperature, heating and cooling protocols) did not reveal any other polymorphs than the one reported in this work.
在标题化合物[CHNCONHCHCH]I或CHNO·I中，一个阳离子和一个阴离子通过强N-H⋯I氢键形成离子对。在晶体中，通过弱C-H⋯I氢键连接的离子对沿晶轴形成无限长链。通过改变结晶溶剂（水、90%丙酮-水、90%乙醇-水、90%异丙醇-水、N,N-二甲基甲酰胺、二甲基亚砜、甲醇、乙腈）和条件（溶液温度、加热和冷却程序）进行多晶型筛选，未发现除本工作报道的多晶型物以外的任何其他多晶型物。
