THE CRYSTAL STRUCTURE OF THE TITLE COMPOUND (SYSTEMATIC NAME: 2-amino-1-methyl-4-oxo-4,5-dihydro-1H-imidazol-3-ium 3-phenyl-prop-2-enoate), C(4)H(8)N(3)O(+)·C(9)H(7)O(2) (-), is stabilized by N-H⋯O hydrogen bonding. Cations are linked to anions to form ion pairs with an R(2) (2)(8) ring motif. These ion pairs are connected through a C(2) (2)(6) chain motif extending along the c axis of the unit cell. This crystal packing is characterized by hydro-phobic layers at x ∼ 1/2 packed between hydro-philic layers at x ∼ 0.
标题化合物（系统命名：2-氨基-1-甲基-4-氧代-4,5-二氢-1H-咪唑-3-鎓 3-苯基-2-烯酸酯），化学式为C(4)H(8)N(3)O(+)·C(9)H(7)O(2) (-)，通过N-H⋯O氢键作用得以稳定。阳离子与阴离子相连形成具有R(2) (2)(8)环 motif 的离子对。这些离子对通过沿晶胞c轴延伸的C(2) (2)(6)链 motif 相连。这种晶体堆积的特征是在x ∼ 1/2处有疏水层堆积在x ∼ 0处的亲水层之间。
