Abstract
In the title ammonium carboxyl-ate-carb-oxy-lic acid co-cystal, C(10)H(9)N(2) (+)·C(8)H(3)I(3)NO(4) (-.)C(8)H(4)I(3)NO(4), the carboxyl-ate anion and carb-oxy-lic acid mol-ecule are linked by O-H⋯O and N-H⋯O hydrogen bonds to form a chain running along the c axis of the monoclinic unit cell. The chains are linked by pyridinum and pyridine N-H⋯O hydrogen bonds, generating a layer motif. O-H⋯N and O-H⋯O hydrogen bonds are also observed.
摘要
在标题为羧酸铵-羧酸共晶体C(10)H(9)N(2) (+)·C(8)H(3)I(3)NO(4) (-.)C(8)H(4)I(3)NO(4)中，羧酸根阴离子和羧酸分子通过O-H⋯O和N-H⋯O氢键相连，形成一条沿单斜晶胞c轴延伸的链。这些链通过吡啶鎓和吡啶N-H⋯O氢键相连，形成层状结构。还观察到O-H⋯N和O-H⋯O氢键。
