In the title salt (common name l-carnitine hydro-chloride), C(7)H(16)NO(3) (+)·Cl(-), the organic cation features a carb-oxy-lic part (-CO(2)H) having unambigous single- and double-bonds [1.336 (2), 1.211 (2) Å]. There is a large N-C-C bond angle [115.9 (1)°] for the C atom connected to the bulky trimethyl-amino substituent. In the crystal, the acid H atom forms a hydrogen bond to the chloride anion, whereas the hydroxyl H atom forms a longer hydrogen bond to the anion, generating a helical chain running along [001].
在标题盐（通用名L-肉碱盐酸盐）C₇H₁₆NO₃⁺·Cl⁻中，有机阳离子的羧酸部分（-CO₂H）具有明确的单键和双键[1.336(2)，1.211(2) Å]。与庞大的三甲氨基取代基相连的C原子的N-C-C键角较大[115.9(1)°]。在晶体中，酸性H原子与氯离子阴离子形成氢键，而羟基H原子与阴离子形成更长的氢键，形成沿[001]方向延伸的螺旋链。
