3-Carboxyanilinium hemioxalate
TL;DRAbstract
In the title compound, C(7)H(8)NO(2) (+)·0.5C(2)O(4) (2-), the asymmetric unit consists of an 3-carboxy-anilinium cation, and one-half of an oxalate anion, which lies on a twofold rotation axis. The crystal packing is consolidated by inter-molecular N-H⋯O and O-H⋯O hydrogen bonds. The structure is built from infinite chains of cations and oxalate anions extending parallel to the b and c axes. The crystal studied was a non-merohedral twin. The ratio of the twin components refined to 0.335 (3):0.665 (3).
