在标题化合物C4 H10 NO3+·C2Cl 3 O2 −（I）中，氨基酸分子以阳离子形式存在，具有带正电荷的氨基和不带电荷的羧酸基团。三氯乙酸分子以阴离子状态存在。苏氨酸阳离子和三氯乙酸阴离子形成氢键双层，通过N-H-O和O-H-O氢键网络连接在一起，并沿着B轴延伸。这些双层之间没有氢键相互作用。在（I）中没有观察到典型的头-尾氢键。
In the title compound, C4H10NO3+·C2Cl3O2−, (I), the amino acid molecule exists in the cationic form, with a positively charged amino group and an uncharged carboxylic acid group. The trichloroacetic acid molecule exists in the anionic state. The threoninium cations and the trichloroacetate anions form hydrogen-bonded double layers, linked together by a network of N—H⋯O and O—H⋯O hydrogen bonds and extended along the b axis. These double layers have no hydrogen-bonded interactions between them. No classic head-to-tail hydrogen bonds are observed in (I).
