Abstract
The asymmetric unit of the title compound, C11H17ClNO+·0.5C2O4 2−, consists of one N-[2-(2-chlorophenyl)-2-hydroxyethyl]propan-2-ammonium cation and one-half of a centrosymmetric oxalate anion. In the cation, the C/C/N plane of the ethylammonium 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 supramolecular tape along the a axis. Between the tapes, a C—H⋯O interaction is observed.
