  摘要：

  分析吡嗪酸1和异构体甲基吡嗪羧酸2-4的X射线晶体结构，以检查在这些杂环酸中羧酸-吡啶超分子合成子V的存在。通过（羧基）OH ... N（吡啶）和（吡啶）CH ... O（羰基）氢键组装的合成子V控制吡啶和吡嗪单羧酸的晶体结构中的自组装。吡啶和吡嗪单羧酸的晶体结构中较常见的酸-酸均二聚体I与酸-吡啶异二聚体V的重复性通过RHF 6-31G *基组中的能量计算来解释。合成子V中的OH.N和CH ... O氢键都是由1-4中活化的酸性供体原子和碱性受体原子产生的。吡嗪2,3-和2，5-二羧酸10和11结晶为二水合物，在合成子VII中具有（羧基）OH ... O（水）氢键，这是二酸结构中的重复模式。总之，羧酸基团在吡嗪单羧酸中形成OH ... N氢键，而在吡嗪二羧酸中形成OH ... O氢键。这种结构分析将分子特征与吡啶和吡嗪羧酸中的超分子合成子相关联，以用于未来的晶体工程策略。
