The asymmetric unit of the title compound, C(11)H(17)ClNO(+)·0.5C(2)O(4) (2-), consists of one N-[2-(2-chloro-phen-yl)-2-hydroxy-ethyl]propan-2-ammonium cation and one-half of a centrosymmetric oxalate anion. In the cation, the C/C/N plane of the ethyl-ammonium group is almost perpendicular to the benzene ring, with a dihedral angle of 88.72 (17)°. In the crystal structure, the two components are connected by O-H⋯O and N-H⋯O hydrogen bonds, forming a supra-molecular tape along the a axis. Between the tapes, a C-H⋯O inter-action is observed.
标题化合物C(11)H(17)ClNO(+)·0.5C(2)O(4) (2-)的不对称单元由一个N-[2-(2-氯苯基)-2-羟基乙基]丙烷-2-铵阳离子和一个中心对称草酸根阴离子的一半组成。在阳离子中，乙铵基团的C/C/N平面几乎垂直于苯环，二面角为88.72 (17)°。在晶体结构中，两种组分通过O-H⋯O和N-H⋯O氢键相连，沿a轴形成一条超分子带。在这些带之间，观察到C-H⋯O相互作用。
