2-Ammonio-3-[(2-ammonioethyl)thio]propionate chloride, C5H13N2O2S+.Cl-, Mr = 200.7, monoclinic, P2(1), a = 5.1275 (4), b = 7.897 (1), c = 11.208 (1) A, beta = 104.129 (8) degrees, V = 440.1 A3, Z = 2, Dx = 1.519 g cm-3, Mo K alpha, lambda = 0.71069 A, mu = 6.12 cm-1, F(000) = 212, T = 295 K, final R = 0.021, wR = 0.027 for 784 reflections with I greater than 3 sigma (I). The two ammonium cations form seven hydrogen bonds: alpha-NH3+ acts as a donor for three carboxylate O atoms and one Cl- ion whereas epsilon-NH3+ is linked to three Cl- ions.
2-氨基-3-[(2-氨乙基)硫代]丙酸氯化物，C5H13N2O2S⁺·Cl⁻，Mr = 200.7，单斜晶系，P2(1)，a = 5.1275(4)，b = 7.897(1)，c = 11.208(1) Å，β = 104.129(8)°，V = 440.1 ų，Z = 2，Dx = 1.519 g cm⁻³，Mo Kα，λ = 0.71069 Å，μ = 6.12 cm⁻¹，F(000) = 212，T = 295 K，对于784个I大于3σ(I)的反射，最终R = 0.021，wR = 0.027。两个铵阳离子形成七个氢键：α-NH3⁺作为三个羧酸根O原子和一个Cl⁻离子的供体，而ε-NH3⁺与三个Cl⁻离子相连。
