1-benz-yloxy-3-methyl-1-oxobutan-2-aminium chloride), C(12)H(18)NO(2) (+)·Cl(-), the ester group is approximately planar, with a maximum deviation of 0.040 (2) Å from the least-squares plane, and makes a dihedral angle of 28.92 (16)° with the phenyl ring. The crystal structure is organized by N-H⋯Cl hydrogen bonds which join the two components into a chain along the b axis. Pairs of chains arranged anti-parallel are inter-connected by further N-H⋯Cl hydrogen bonds, forming eight-membered rings. Similar packing modes have been observed in a number of amino acid ester halides with a short unit-cell parameter of ca 5.5 Å along the direction in which the chains run.
1-苄氧基-3-甲基-1-氧代丁烷-2-铵氯化物，C(12)H(18)NO(2)(+)·Cl(-)，酯基近似平面状，与最小二乘平面的最大偏差为0.040 (2) Å，与苯环形成的二面角为28.92 (16)°。晶体结构由N-H⋯Cl氢键构成，这些氢键将两个组分沿b轴连接成链。反平行排列的链对通过进一步的N-H⋯Cl氢键相互连接，形成八元环。在许多氨基酸酯卤化物中观察到了类似的堆积模式，沿链的方向晶胞参数短，约为5.5 Å。
